1. Answer: Newton's third law

Explanation:

The forces on both cannon and ball are equal, but they do not have equal acceleration.

Newton's third law states that for every action there must be an equal and opposite reaction, so the forces on the cannon and cannonball are equal in magnitude (but not direction).

The acceleration for both objects are not equal as:

acceleration = force/mass

and the mass of the cannon is larger than the mass of the cannonball, so the acceleration is lesser for the cannon than for the cannonball.



2. Answer: Newton's Third Law

Explanation: Seat belts stop you tumbling around inside the car if there is a collision. Upon sensing a collision the seat belts lock in place. When the car crashes, there is no unbalanced force acting on the person, so they continue forward (Newton's First Law). The person moves against the seat belt, exerting a force on it. The seat belt then exerts a force back on the person (Newton's Third Law). This causes a controlled deceleration of the person.

Akeem is walking on the beach on a hot summer day. The sand is very hot, so he runs and puts his feet in the water, which is muc
kramer

Sample Response: The water is cooler than the sand because it has a higher specific heat value. This means that it takes longer for the water to increase in temperature, making it feel cooler than the sand, which warms up more quickly.

A circular loop of radius 0.0400 m is
Alenkinab [10]

Let's see

Find enclosed area of loop

\\ \rm\dashrightarrow \pi r^2

\\ \rm\dashrightarrow 3.14(0.04)^2

\\ \rm\dashrightarrow 0.005m^2

Now

\\ \rm\dashrightarrow \phi=BAcos\theta

  • We need B

\\ \rm\dashrightarrow 9.59\times 10^{-7}=B(0.005)cos75

\\ \rm\dashrightarrow 9.59\times 10^{-7}=0.0046B

\\ \rm\dashrightarrow B=2084.78\times 10^{-7}

\\ \rm\dashrightarrow B=2.08\times 10^{-4}T

\\ \rm\dashrightarrow B=0.208mT

A rock dropped down a well takes 1.8 s to hit the water. How far below the top of the well is the surface of the water
Brut [27]

Answer: 15.87 m

From the equation of motion:

s=ut+\frac{1}{2}at^2

where, s is the distance traveled, u is the initial velocity, a is the acceleration and t is the time.

The rock free falls under gravity. Initial velocity, u=0 m/s, a=g=9.8m/s^2

It took t=1.8 s for rock to hit the water.

Substitute the values in the given equation:

\Rightarrow s=0+\frac{1}{2}9.8m/s^2\times(1.8s)^2=15.87 m

Hence, the water is 15.87 m below the top level of the well.
