Hey bro here's the answer

The answer is 1.66m/s^2 and 99.6 N

Explanation:

Solu

Here,

Mass of the Moon (M)=7.2 ×10^22 kg

Radius(R) = 1.7 × 10^6 m

Gravitational constant (G)=6.67×10^-11 Nm2/kg2

Acceleration (a)=?

We know that ,

g moon =GM/r^2

=6.67 ×10^-11 ×7.2 ×10^22

______________________

(1.7×10^6)2

=48.024 ×10^-11+22

__________________

2.89 ×10^12

= 16.61 ×10^-11+22-12

=16.61×10^-1

= 1.66 m/s2

Now,

weight of man (w)= m × g

= 60 × 1.66

= 99.6N

:. Weight if man is 99.6 N and acceleration due to gravity is 1.66 m/s2

Answer:

The distance the plane covered while it was accelerating is 80,633.3 m

Explanation:

Given;

initial velocity of the plane, u = 90 m/s

acceleration of the plane, a = 1.5 m/s²

final velocity of the plane, v = 500 m/s

The distance covered by the plane is given as;

v² = u² + 2ad

where;

d is the distance covered by the plane;

500² = 90² + 2(1.5)d

500²  - 90² = 3d

241900 = 3d

d = 241900 / 3

d = 80,633.3 m

Therefore, the distance the plane covered while it was accelerating is 80,633.3 m

The correct answer is option C: polar, tropic, temperature, polar. The Earth is divided into different climatic zones based on the amount of sunlight received by different regions.

These zones are classified into three broad categories: polar, temperate, and tropical. Starting from the North Pole and moving towards the South Pole, the first zone encountered is the polar zone. This zone is characterized by extremely cold temperatures and receives very little sunlight throughout the year. The next zone encountered is the tropic zone, which lies between the Tropic of Cancer and the Tropic of Capricorn. This zone receives the most sunlight and is characterized by hot temperatures. Finally, the last zone encountered is the polar zone, which is similar to the first zone encountered but at the opposite end of the Earth. Therefore, the correct order of zones from the North Pole to the South Pole is polar, tropic, temperature, and polar.

Answer:

Explanation:

An egg is dropped from a treehouse and takes 5 seconds to reach the ground. Air resistance can be ignored. The displacement of the egg will be 122.5m.

This question is from the branch of physics called kinematics. We use equations of motion to find out the unknown quantity from the given data. Let us use the equation of motion, s=ut+1/2*a*t²

where, s is the displacement of the egg in metres

u is the initial velocity of the egg in m/s

a is the acceleration in m/s²

t is the time in seconds

As we know that, the egg is in a freefall condition, its initial velocity is zero and acceleration is nothing but acceleration due to gravity here as it is under the action of gravity.

s=1/2*g*t²

s=1/2*9.8*5*5

s=122.5m

So, the displacement of the egg is 122.5m.

The magnitude of the average acceleration is 2.5 m/s²

Acceleration refers to the ratio of  velocity changes with to time. if it speeds up or slows down, the object moving in a straight line is accelerated . Motion along a circle is accelerated even if the speed is constant, due the constantly changing direction. Both effects contribute to the acceleration for all other kinds of motion, .

It is a vector quantity because it have both a magnitude and a direction, . Velocity is also a vector quantity. Acceleration is defined as the change in velocity vector over the time interval divided by the time interval.

a =  \(\frac{v-u}{t}\) m/s²

a = acceleration

v = final velocity of object

u = initial velocity of object

For the given question:

a = \(\frac{25-15}{4}\)  m/s²

a = \(\frac{10}{4}\)  m/s²

The answer is D: 4.8x 10⁻¹³N right

The magnetic force is given as: F = qvBsinФ

where Ф is the angle between magnetic field (B) & the velocity of charge (v).

Since there is no Ф given, we assume, Ф = 90.

And we know, sin 90 = 1, we get,

⇒ F = qvB

⇒ F = 1.6×10^(-19) C ×2.5×10^(7)×0.12 T

⇒ F = 0.48 × 10^(-12)

or F = 4.8 × 10^(-13)

Now, using Fleming's Left Hand Rule to find the direction (right).

Thus the answer is D= 4.8x10⁻¹³N right

Answer:

Newton's Third Law of Motion

Explanation:

Newton's Third Law of Motion which states that, for every action there is an equal but opposite reaction.

This ultimately implies that, in every interaction, there is a pair of forces acting on the two interacting objects.

In this scenario, a ball bounced by a basketball player on the floor bounces back up at her.

According to Newton's Third Law of Motion, the statement above simply means that in every interaction, there is a pair of forces acting on the two interacting objects i.e the ball and floor. The size of the force on the ball equals the size of the force on the floor. These two forces are called action and reaction forces and are the subject of Newton's third law of motion.

Hence, the ball bounced by the basketball player on the floor would bounce back in equal magnitude.

An elliptical orbit is an oval-shaped path that a satellite takes around its primary body, such as the Earth. The speed of a satellite in its orbit varies depending on its distance from the primary body, which changes throughout the elliptical orbit.

According to Kepler's laws of planetary motion, a satellite moves fastest when it is closest to the primary body, and slowest when it is farthest away. Therefore, an Earth satellite has the greatest speed at the point in its orbit called perigee, which is the point where it is closest to the Earth. At perigee, the satellite experiences the strongest gravitational pull from the Earth, which accelerates it and increases its speed.

Conversely, the satellite has the least speed at the point called apogee, which is the farthest point in its orbit from the Earth. At apogee, the satellite experiences the weakest gravitational pull from the Earth, which decelerates it and decreases its speed.

It's important to note that the speed of a satellite in orbit is also affected by other factors, such as the presence of other gravitational bodies and atmospheric drag. However, the varying distance from the primary body is the primary factor affecting the speed of a satellite in an elliptical orbit around the Earth.

Answer:

B

Explanation:

The weight of a person weighing 580.00 newtons (about 130 pounds) at a beach near San Diego would be slightly less at Big Bear Lake, which is about 2000 meters high.

To calculate the weight at Big Bear Lake, we need to consider the change in gravitational force with altitude. The weight of an object is given by the equation:

Weight = Mass x Acceleration due to gravity

Since mass remains constant, the change in weight is solely dependent on the change in acceleration due to gravity. As we go higher above sea level, the acceleration due to gravity decreases slightly.

To calculate the weight at Big Bear Lake, we can use the formula:

Weight at Big Bear Lake = Weight at sea level x (Acceleration due to gravity at sea level / Acceleration due to gravity at Big Bear Lake)

The acceleration due to gravity at sea level is approximately 9.81 m/s^2, and the acceleration due to gravity at Big Bear Lake would be slightly less due to the increase in altitude.

By substituting the values and calculating, we can determine the weight at Big Bear Lake.
