A baseball weighs 0.15kg and has a south momentum of 6.0kg m/s. The speed of the baseball was (v) = 40 m/s south.

It's a physical magnitude that measures the product of the mass by the velocity of a particle. Its units in the International System is kg. m/s and the formula is

p = mv

where

m is the mass of the object

v is its velocity

In this problem, we know:

p = 6.0 kg m/s is the momentum of the baseball

m = 0.15 kg is its mass

Therefore, we can re-arrange the equation to find the baseball's velocity:

v = p/m

v = 6.0/0.15

Answer: 20.73m/s

Explanation:

The question simply wants us to calculate the speed of the pitch. The speed will be calculated as:

= Distance/Time

where,

Distance = 85 meters

Time = 4.1 seconds

Speed = Distance/Time

Speed = 85/4.1

Speed = 20.73m/s

Therefore, the speed of the pitch is 20.73m/s.

When you move a stretched out light spring one end attached to a wall lying in z-axis along z-axis, you get a longitudinal wave and when along x-axis or y-axis, you get a transverse wave.

When you move the free end of the spring along the z axis (the axis along which the spring is stretched), you create a longitudinal wave. This is because the displacement of the spring particles is in the same direction as the direction of wave propagation.

When you move the free end of the spring along the x axis, you create a transverse wave. This is because the displacement of the spring particles is perpendicular to the direction of wave propagation.

When you move the free end of the spring along the y axis, you create a transverse wave. Similarly to x axis, the displacement of the spring particles is perpendicular to the direction of wave propagation.

Answer:

C. A turtle relies indirectly on the Sun as an energy source.

Explanation:

Turtles are animals, meaning they are unable to perform photosynthesis, thus option A is inapplicable. Turtles consume food such as algae and seagrass. These aquatic plants gain their energy directly from the Sun through photosynthesis, and as a result when the turtle consumes these plants, that energy from the Sun is indirectly feeding the turtle.

Thermal energy increases during melting.

When ice melts during melting, its temperature remains constant until all the ice turns into water. Then, heating of liquid water causes the molecules to vibrate faster and steadily increasing the temperature.

Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. A branch of physics, thermodynamics, concerns with how heat is transferred among different systems.

An example of thermal energy is boiling water on a stove. When boiling water, thermal energy is produced when the atoms and molecules in a substance vibrate faster because of raising in temperature.

0.08 m/s2 is the average acceleration. The acceleration's degree of uncertainty is 0.0135 m/s2.

Accelerations are included in vector quantities. An object's acceleration in relation to a net force is determined by the direction of that force. Force imbalances lead to acceleration in a body.

Uniform, non-uniform, and average acceleration are the three primary types of accelerated motions. It is said to have uniform acceleration when an object moves in a straight line with an increase in speed that happens at regular intervals of time.

Acceleration is the term used to describe any change in the speed or direction of a motion. Anything that is accelerating is moving faster, slower, or in a direction other than straight forward.

The graph that best illustrates how the intensity of sound varies as a detector is moved further and further from a stationary source projecting sound in all directions would be an inverse square law graph. This graph would show that the intensity of sound decreases as the distance from the source increases. The intensity of sound is inversely proportional to the square of the distance from the source.

This means that if the distance from the source is doubled, the intensity of sound is decreased by a factor of four. This relationship is commonly observed in physics and engineering and is known as the inverse square law of sound propagation. This law states that the intensity of sound decreases as the distance from the source increases in a manner that is inversely proportional to the square of the distance.

A skier of mass m starts from rest at the top of a solid sphere of radius r and slides down its frictionless surface.

The net force on the skier in the radial direction must be equal to the centripetal force in order to sustain circular motion.

where [tex]v[/tex] denotes the skier's tangential instantaneous speed. Gravity and the normal force are the two forces at work on the skier. While the gravitational force is constantly radially outward, the normal force is always dependent on the angle [tex]\theta[/tex]. Therefore, the net force in the radial direction is, if the skier is at an angle of [tex]\theta[/tex] down the sphere.

[tex]$F_{\text {radial }}=m g \cos \theta-N$[/tex]

where N is the normal force's magnitude. When these two equations are combined, we get,

[tex]$\frac{m v^2}{r}=m g \cos \theta-N$[/tex]

Using the principle of energy conservation, we now substitute v with values we already know. The loss of potential energy equals the increase in kinetic energy, which on a sphere is written as,

[tex]$\frac{1}{2} m v^2=m g r(1-\cos \theta)$[/tex]

As the skier begins at rest, there is no kinetic energy at the top of the sphere. After removing [tex]v^2[/tex], we are left with the equation,

[tex]$2 m g(1-\cos \theta)=m g \cos \theta-N$[/tex]

Quantifying the situation when the skier exits the sphere is the last aspect of the issue. We can see that when theta equals 0, we get N = mg, which means that the normal force acting on the skier precisely balances the force of gravity. N decreases as the skier descends the sphere's surface, balancing the equation until it equals zero at a certain angle. This occurs precisely when,

[tex]$2 m g(1-\cos \theta)=m g \cos \theta$[/tex]

The skier is no longer in contact with the sphere when the normal force acting on the skier is zero, as the sphere no longer exerts any force on the skier. This is assumed to be the prerequisite for the skier to leave the ground.

After calculating [tex]\theta[/tex], we have,

[tex]$2 m g=3 m g \cos \theta$[/tex]

[tex]$\Longrightarrow \theta=\cos ^{-1}(2 / 3) \approx 48.19^{\circ}$[/tex]

First, we can note that this response is unaffected by the physical parameters m, r, and g. No matter how heavy he is, how huge the sphere is, or how powerful gravity is, the skier will exit the sphere at the same angle.

However, we will discover from dimensional analysis that this independence is actually not all that remarkable. Consider the units of the variables we've provided,

[tex]$[m]=$ kilograms,$\quad[r]=$ meters,$\quad[g]=$ meters $\cdot$ seconds $^{-2}$[/tex]

Any algebraic statement containing m, r, and g cannot be transformed into a dimensionless quantity. As a result, we draw the conclusion that the solution to our problem cannot depend on these values as an angle is a dimensionless quantity.

Answer:

1.04 x 10-3 J.

Explanation:

The total rotational kinetic energy of the two hands about the axis of rotation is calculated using the formula:

Kinetic Energy = 1/2 I ω2,

where I is the moment of inertia and ω is the angular velocity.

For this scenario, the moment of inertia is calculated by

I = 1/3 ML2,

where M is the total mass and L is the length of the arm.

Since the total mass of the two hands is 169.5 kg, and the length of the arms is 2.71 m and 4.4 m, the moment of inertia is calculated to be I = 5.35 x 10-5 kg m2. Substituting this value of I into the equation, the total rotational kinetic energy of the two hands about the axis of rotation is calculated to be 1.04 x 10-3 J.

The momentum of the rock by the student is 0.500kgm/s.

Momentum -

momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum. Check out Newton's laws of motion.

Momentum can be viewed as a body's "power" while it is moving, or the amount of force it can exert on another body. For instance, a baseball (small mass) thrown quickly can have the same momentum as a bowling ball (big mass) going extremely slowly (low velocity) (high velocity).

Momentum = Mass × Velocity

Momentum of rock = 0.500 × 1

= 0.500kgm/s

Momentum of Boy = 45 × 0 [As boy is at rest so, he has 0 momentum]

Momentum of boy = 0
