The angular speed of Earth is 1.99 x 10-7 radians /seconds.
Yes, that is correct. The angular speed of Earth is 1.99 x 10-7 radians per second. This is equal to 2π radians per year, or 1 revolution per 365.25 days.
The angular speed of the Earth is the rate at which it rotates around its own axis. It is measured in radians per second, and is typically expressed as 2π radians per day, or 7.27 x 10-5 rad/s. The angular speed of the Earth is constant, meaning that it does not change over time. This is important, as it allows us to measure the length of a day and use this to calculate the rate of other processes such as the seasons and the passage of time.

Suppose three forces are acting on a model rocket launching into the air. The force of gravity is 1.2 N acting downward. The rocket engine has a force of 12.3 N acting at an angle of 65⁰ above the horizontal to the right. The wind pushes the rocket with a force of 2.5 N to the left. Find the magnitude and direction of the resultant force on the rocket.
Please answer!!! Offering 50 points for answer and explanation
Answer:
can you include a picture
Decompose the forces acting on the rocket in horizontal and vertical components.
• net horizontal force:
∑ F = (12.3 N) cos(65°) - 2.5 N ≈ 2.7 N
(notice we're taking "to the right" to be the positive direction)
• net vertical force:
∑ F = (12.3 N) sin(65°) - 1.2 N ≈ 9.9 N
The resultant force then has magnitude
√((2.7 N)² + (9.9 N)²) ≈ 10.3 N
Since the horizontal and vertical components of the resultant are both positive, it points at an angle between 0° and 90° from the positive horizontal, so that
tan(θ) ≈ (9.9 N) / (2.7 N) ≈ 3.69
===> θ ≈ arctan(3.69) ≈ 75°
When a pitcher throws a baseball, it reaches a top speed of 39 m/s. If thebaseball takes 1.5 seconds to travel from the pitcher to the catcher, what isits acceleration? (Assume the ball is moving at 0 m/s right before it leavesthe pitcher's hand.)A. 23 m/s2B. 17 m/s2C. 11 m/s2D. 26 m/s2
Given,
The final velocity of the ball, v=39 m/s
The initial velocity of the ball, u=0 m/s
The time duration, t=1.5 s
The final velocity of an object upon which an accleration, a, acts for a duration of t seconds is given by one of the equations of motion as
\(v=u+at\)By substituting the known values and simplifying the resulting equation we will get the acceleration of the ball.
Thus,
\(\begin{gathered} 39=0+a\times1.5 \\ \Rightarrow a=\frac{39}{1.5} \\ 26m/s^2 \end{gathered}\)Thus the acceleration of the ball is 26 m/s²
Therefore the right answer is option 4.
A Student 330 m 990m from another tall flip between the the Student stands Sound Interval beteeen cliff is cliff from of 1 st and 630 tall Hip which speed of 330 if the 330 m/s 2nd eh what is echo?
The interval between the first and second echo is 7 seconds. This means that after the initial sound wave reaches the first cliff, it takes a total of 7 seconds for the sound to travel to the second cliff and then return to the student as the second echo.
To determine the interval between the first and second echo, we need to consider the time it takes for sound to travel from the student to the first cliff, and then from the first cliff to the second cliff, and finally back to the student.
Let's break down the distances and calculate the time for each part of the journey:
Distance from the student to the first cliff: 330 meters
Time taken: t₁ = distance / speed = 330 m / 330 m/s = 1 second
Distance from the first cliff to the second cliff: 990 meters
Time taken: t₂ = distance / speed = 990 m / 330 m/s = 3 seconds
Distance from the second cliff back to the student: 990 meters
Time taken: t₃ = distance / speed = 990 m / 330 m/s = 3 seconds
Now, we can calculate the total interval between the first and second echo by adding up the individual times:
Interval between first and second echo = t₁ + t₂ + t₃ = 1 s + 3 s + 3 s = 7 seconds
Therefore, the interval between the first and second echo is 7 seconds. This means that after the initial sound wave reaches the first cliff, it takes a total of 7 seconds for the sound to travel to the second cliff and then return to the student as the second echo.
It's important to note that this calculation assumes a straight path for the sound waves and neglects factors such as air temperature and wind that can affect the speed of sound. Additionally, it assumes perfect reflection of sound waves off the cliffs, which may not be the case in real-world scenarios.

What is the net (unbalanced) force acting on the wagon?
What forces are acting on the wagon?
If the mass on the wagon increased, use Newton's law to explain what must change to get the object moving at constant speed.
The forces acting on the wagon are the applied horizontal force, gravitational force and the friction. To maintain a constant speed after the mass is changed, the acceleration must be reduced to move in a constant speed.
What is net force?Force is an external agent acting on a body to change its motion or to deform it. There are various kind of forces such as friction, gravitational force, magnetic force etc.
The net force on an object is dependent on the magnitude and direction of all the forces acting on it. Here, the gravitational force will balance the applied horizontal force if the weight is greater.
The forces acting on the wagon are applied horizontal force, gravitational force and the friction. According to Newton's second law of motion, the force is the product of mass and acceleration.
If the mass is increased, the force applied must be balanced to make the acceleration unchanged with a constant velocity.

masses join together, what is their velocity after collision?
O-0.33 m/s
O-0.20 m/s
O +1.4 m/s
O +2.3 m/s
Answer:
- 0.33 m/s
Explanation:
An illustration is shown above,
In this case, since the two objects move in opposite directions before collision, then move together, the formula to be used is,
m1u1 - m2u2 = (m1 + m2)v
Where,
m1 = mass of the first object
u1 = initial velocity of the first object
v1 = final velocity of the first object
m2 = mass of the second object
u2 = initial velocity of the second object
v2 = final velocity of the second object
Therefore,
(4.0 • 3.0) - (8.0 • 2.0) = (4.0 + 8.0)v
12 - 16 = 12v
-4 = 12v
Divide both sides by 12,
-4 / 12 = 12v / 12
-1 / 3 = v

How long will it take to heat 0.71kg of water (c=4200J/kgK) from room temperature (20°C) to its boiling point if it were put in a 600W microwave
6.64 minutes to heat 0.71kg of water from 20°C to its boiling point using a 600W microwave.
To calculate the time it takes to heat the water, we can use the formula:
Q = mcΔT
where Q is the heat energy absorbed by the water, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.
First, let's find the change in temperature:
ΔT = boiling point - room temperature = 100°C - 20°C = 80°C
Next, we can calculate the heat energy absorbed:
Q = mcΔT = (0.71kg)(4200J/kgK)(80°C) = 239,040J
Now, let's find the time it takes to supply this amount of energy using a 600W microwave:
Power (P) = Energy (Q) / Time (t)
t = Q / P = 239,040J / 600W = 398.4 seconds
Therefore, it will take approximately 398.4 seconds or 6.64 minutes to heat 0.71kg of water from room temperature to its boiling point using a 600W microwave.
It's worth noting that this calculation assumes all the microwave's power is effectively transferred to the water and that there are no heat losses during the process. In practice, factors like heat transfer efficiency and losses should be considered, which may slightly affect the actual heating time.

SI units refer to the International System of Units. These are the standard units that measurements are typically given in. For example, the SI unit for time is seconds, meters for distance, kg for mass, etc.
Significant figures are the number of notable digits given for a measurement. For example, let's say you measured a piece of metal to be exactly 3.00 meters long. The value 3.00 has three significant figures, where as 3 only has one significant figure. Larger amounts of significant figures indicate a more precise measurement.

Two objects (42.0 and 21.0 kg) are connected by a massless string that passes over a massless, frictionless pulley. The pulley hangs from the ceiling. Find (a) the acceleration of the objects and (b) the tension in the string.
Answer:
a = 3.27 m/s²
T = 275 N
Explanation:
Given that:
Mass m₁ = 42.p0 kg
Mass m₂ = 21.0 kg
Consider both masses to be in a whole system, then:
The acceleration can be determined as:
\((m_1+m_2)a = g(m_1-m_2)\)
Making acceleration the subject in the above formula;
\(a =\dfrac{g(m_1-m_2)}{(m_1+m_2)}\)
\(a =\dfrac{9.8(42.0-21.0)}{(42.0+21.0)}\)
\(a =\dfrac{9.8(21.0)}{(63.0)}\)
\(a =\dfrac{205.8}{(63.0)}\)
a = 3.27 m/s²
in the string, the tension is calculated using the formula:
\(T = \dfrac{2m_1m_2g}{(m_1+m_2)}\)
\(T = \dfrac{2(42)(21)(9.81)}{(42+21)}\)
\(T = \dfrac{17304.84}{63}\)
T = 274.68 N
T ≅ 275 N
The speed of light is 3×10^8 meters per second, which means that light can travel 300 million meters in just one second. How far can light travel in one minute?
Answer:
(1.8 × 10^9) meters in one minute
Explanation:
To determine how far light can travel in one minute, we need to multiply its speed by the number of seconds in a minute.
The speed of light is 3 × 10^8 meters per second.
There are 60 seconds in a minute.
Therefore, the distance light can travel in one minute is:
Distance = Speed × Time
Distance = (3 × 10^8 meters per second) × (60 seconds)
Calculating this, we get:
Distance = 3 × 10^8 meters/second × 60 seconds
Distance = 18 × 10^8 meters
Distance = 1.8 × 10^9 meters
So, light can travel approximately 1.8 billion (1.8 × 10^9) meters in one minute.

7. Using the idea of Impulse, explain why a field goal kicker should 'kick through the ball', meaning extend their foot
as high up as possible at the end of the kick.
Answer:
Impulse is the amount of force put on an object in a certain amount of time. Therefore when kicking a ball and "kicking through it" it extends the period of time this force is applied in turn increasing its impulse. Impulse is equal to change in momentum. momentum is equal to mass times velocity and since mass of the ball doesn't change therefore the velocity is increased and performance increased.

Refer to a long, straight wire carrying constant current I. What can be concluded about the magnitude of the magnetic field at distance a from the wire?
Answer:
"the magnitude of the magnetic field at a point of distance a around a wire, carrying a constant current I, is inversely proportional to the distance a of the wire from that point"
Explanation:
The magnitude of the magnetic field from a long straight wire (A approximately a finite length of wire at least for close points around the wire.) decreases with distance from the wire. It does not follow the inverse square rule as is the electric field from a point charge. We can then say that "the magnitude of the magnetic field at a point of distance a around a wire, carrying a constant current I, is inversely proportional to the distance a of the wire from that point"
From the Biot-Savart rule,
B = μI/2πR
where B is the magnitude of the magnetic field
I is the current through the wire
μ is the permeability of free space or vacuum
R is the distance between the point and the wire, in this case is = a
If a bus is traveling at 12m/s and a passenger on the bus is walking to the back of the bus at a velocity of 5m/s, what is the relative velocity of the passenger relative to the ground?
The relative velocity is 17m/s.
The relative velocity of the passenger relative to the ground can be found by applying the concept of relative motion.
speed of bus (vb)=12m/s
speed of passenger inside the bus(vp)= 5m/s opposite to the speed of bus
speed of passenger relative to the ground = v
v= vb+vp
v= 12+(-5), since passenger is traveling in opposite direction
v=7m/
Therefore, the velocity of passenger relative to the ground is 7m/s.

The earthquake would occur 13 minutes before 10:05 a.m. which will be at 9.52 am.
The p-waves travel with a constant velocity of 7 km/s
The time can be calculated by using the formula
t = d / v
where
T1 = 10:05 a.m
d is the distance they take to travel from the epicenter
v is the speed of the p-waves
On average, the speed of p-waves is
v = 7 km/s
d = 5600 km (given)
Substituting the values in the formula;
t = d / v
t = 5600 ÷ 7
t = 800 seconds
Converting into minutes,
t = 800 ÷ 60
t = 13.3
≈ 13 mins
T1 - 13 mins = T2
10:05 - 13 mins = 9.52 am
