He throws a baseball 59 m to brandon at second base, creating a 30 degree angle east of south. brandon then turns and throws baseball 55 m east to first base the displacement  of the baseball is S = 89.75m

The following equation represents the ball's vertical velocity:

v2 = u₂- sinα2gh

The vertical component of the velocity vector at time t is denoted by v2.

u2 = initial velocity.

α = throwing angle.

-10 m/s2 if you consider the upward direction to be positive) is the acceleration caused by gravity.

t = time.

The ball's vertical velocity is zero when it reaches the highest point along its path. In order to find the initial velocity, we can use the equation for vertical velocity:

v2 = u₂- sinα2gh

0= u₂×sin(30°) 2 ×10m/s²×55

1100 sin(30°) = u2

1100/2 = u2

550 = u2

u = 23.4 m/s

At 23.4 m/s, the ball flies out of your grasp.

t = d/s

If no additional protection is provided, the largest size hole that can be used in a nominal 1.5-inch by 3.5-inch wood stud is 1 inch.

If no additional protection is provided, the largest size hole that can be used in a nominal 1.5-inch by 3.5-inch wood stud is typically 1 inch. This is based on the general rule of thumb in construction, which states that the maximum hole size should not exceed one-third the depth or width of the stud. In this case, the depth of the stud is 1.5 inches, so one-third of that is 0.5 inches. Similarly, the width of the stud is 3.5 inches, so one-third of that is approximately 1.17 inches.

Since 1 inch is smaller than both 0.5 inches and 1.17 inches, it is the maximum allowable hole size for the given stud. It's important to note that this rule assumes no additional protection is provided, such as metal plates or fire-resistant coatings.

48 m/s in terms of km/h is 720.8 km/h. In terms of m/min is 2880 m/min, in terms of km/s is 0.048 km/s and in terms of km/min is 2.88 km/min.

To solve this question, we need to understand some terms. The unit of velocity is measured in m/s. It can be expressed in different units of velocity.

1 km (kilometer) = 1000 meter

1 h (hour) = 3600 seconds

1 minutes = 60 seconds

To convert m/s into km/h,

48 m/s * 3600/1000 =  172.8 km/h

To convert m/s into m/min,

48 m/s * 60 = 2880 m/min

To convert m/s into km/s,

48 m/s ÷ 1000 = 0.048 km/s

To convert m/s into km/minutes,

48 m/s * 60 / 1000 = 2.88 km/min

Therefore, the 48 m/s expressed is 172.8 km/h, 2880 m/min, 0.048 km/s and 2.88 km/min.

48 m/s is equivalent to  172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

To express 48 m/s in different units of velocity:

km/h (kilometers per hour):

To convert m/s to km/h, we can use the conversion factor of 3.6 since 1 m/s is equal to 3.6 km/h.

48 m/s * (3.6 km/h / 1 m/s) = 172.8 km/h

Therefore, 48 m/s is equivalent to 172.8 km/h.

m/min (meters per minute):

To convert m/s to m/min, we can use the conversion factor of 60 since there are 60 seconds in a minute.

48 m/s * (60 m/min / 1 s) = 2880 m/min

Therefore, 48 m/s is equivalent to 2880 m/min.

km/s (kilometers per second):

Since 1 kilometer is equal to 1000 meters, to convert m/s to km/s, we divide the value by 1000.

48 m/s / 1000 = 0.048 km/s

Therefore, 48 m/s is equivalent to 0.048 km/s.

km/minute (kilometers per minute):

To convert m/s to km/minute, we first need to convert m/s to km/s (as calculated in the previous step) and then multiply by 60 to convert seconds to minutes.

0.048 km/s * 60 = 2.88 km/minute

So, 48 m/s is equivalent to 2.88 km/minute.

Hence, 48 m/s is equivalent to approximately 172.8 km/h, 2880 m/min, 0.048 km/s, and 2.88 km/minute.

The unit in which force is measured.

A newton is the unit in which force is measured because it represents the amount of force required to accelerate a 1 kilogram mass at a rate of 1 meter per second squared. In other words, it is the force needed to cause a mass of 1 kilogram to accelerate at a rate of 1 meter per second squared. This relationship between force, mass, and acceleration is described by Newton's second law of motion. The unit is named after Sir Isaac Newton, a physicist and mathematician who formulated the laws of motion.

The maximum possible speed of the electron is approximately 1.57 million meters per second.

The maximum possible speed of the electron can be calculated using the equation:
Maximum kinetic energy of the electron = Energy of the photon - Work function of silver
The energy of a 5.2 ev photon is 5.2 electron volts. The work function of silver is typically around 4.7 electron volts.
So, the maximum kinetic energy of the electron = 5.2 - 4.7 = 0.5 electron volts.
We can then use the equation:
Maximum kinetic energy of the electron = 0.5 \(mv^{2}\)
where m is the mass of the electron and v is its speed.
The mass of an electron is approximately 9.11 x \(10^{-31}\) kg.
Rearranging the equation gives:

In a 5.0 L container at 373 K and 203 KPa there is 0.327 mol of a gas sample.

The number of moles of a gas sample in a container can be calculated using the ideal gas law, which is represented by the equation PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature.

Given the volume (V) of the container as 5.0 L, the temperature (T) as 373 K, and the pressure (P) as 203 kPa, we can rearrange the ideal gas law equation to solve for the number of moles (n) as follows:
n = PV/RT

Substituting the given values into the equation, we get:

n = (203 kPa)(5.0 L)/ (8.314 L*kPa/K*mol)(373 K)

n = 1015 kPa*L / (8.314 L*kPa/K*mol)(373 K)

Answer:

The horizontal speed of the ball is constant where there is little resistance from the air

Explanation:

From the given parameters of the ball, we have;

The horizontal speed of the ball = 4.0 m/s

The height of the cliff from which the ball is launched = 24.6 meters

The direction in which the ball is launched = Horizontally

The components of the forces acting on the ball are;

The vertical force = The Earth's gravitational attraction

The horizontal force = 0 N (There are no horizontal forces acting on the ball)

According to Newton's first law of motion, the ball will continue in its uniform motion or in its rest state unless acted upon by a force

Therefore, given that there are no horizontal forces component acting on the ball, (little air resistance) the ball will continue with the initial horizontal velocity, such that the horizontal velocity of the ball remains constant.

Newton's Second Law of Motion states that the net force acting on an object is directly proportional to its acceleration. The proportionality constant, which is the object's mass, gives the equation ma = f (force equals mass times acceleration). This means that if a force is applied to an object with a certain mass, it will accelerate proportionally to the magnitude of the force.

Applying Newton's Second Law of Motion allows us to determine the force required to move an object of a certain mass a certain distance. We can also use it to calculate the acceleration of an object given its mass and the force acting on it. The second law states that the acceleration of an object is proportional to the force applied to it and inversely proportional to its mass. If the mass of the object remains constant, the acceleration produced is directly proportional to the force applied.

The second law also tells us that if a net force is acting on an object, it will accelerate in the direction of that force. This law can be used to explain the motion of objects in both linear and rotational motion. For example, when a bat hits a ball, the force of the bat on the ball causes it to accelerate, and the ball moves in the direction of that force. In summary, applying Newton's Second Law of Motion is a powerful tool for understanding the motion of objects and how they respond to forces acting on them.
