Question
What are the 3 laws of Newton
Solution 1

What are Newton's 1st 2nd and 3rd laws of motion?

They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. More precisely, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn't exist.

Question
83. A racquet ball is struck in such a way that it leaves the racquet with a speed of 4.87 m/s in the horizontal direction. When the ball hits the court, it is a horizontal distance of 1.95 m from the racquet. Find the height of the racquet ball when it left the racquet.
Solution 1

The height of the racquet ball  is 0.8 m.

Since the ball hits the court at a horizontal distance of 1.95 m from the racquet, hence the range is 1.95 m.

Range = velocity * time

1.95 = 4.87 * t

t = 0.4 s

Hence it took 0.4 s for the ball to land. The height (h) is:

h = (1/2)gt²

but g = acceleration due to gravity = 10 m/s², hence:

h = (1/2)*10*0.4² = 0.8 m

Therefore the height of the racquet ball  is 0.8 m.

Solution 2

0.7864m

Explanation:

Ignore air resistance (the ball's horizontal speed stays constant), the time it takes for the ball to travel 1.95 m horizontally at the rate of 4.87 m/s.

t = 1.95 / 4.88 = 0.4s

This is also the time it takes to fall vertically with gravitational acceleration of g = 9.81 m/s2. We can use the following equation of motion to estimate the vertical distance:

Question
Explain how the principle of uniformitarianism would help geologists determine the source of a layer of particular igneous rock ?
Solution 1

The uniformitarianism principle would aid geologists in determining the origin of a layer of specific igneous rock that rocks changing forms.

### What is uniformitarianism?

Uniformitarianism provided us with a tool for interpreting the geologic past. In fact, geologists frequently summarize the concept as "the gift is the crucial component to the past." The concept is used to describe all types of tectonic processes. The other major tenet of uniformitarianism is that the Earth is a very old place.

The best approach to the past is in the present. He referred to this as the concept of uniformitarianism. It is that if we can comprehend a geomorphological process now and find proof of that same methodology in the past, we can presume that the process worked similarly in the past.

Therefore, it can be concluded that  rocks changing forms helps to understand the concept of uniformitarianism that helps in the identification of the rocks.

Solution 2

Uniformitarianism gave us a tool to interpret the geologic past. In fact, geologists sometimes summarize the concept in the phrase: The present is the key to the past. The concept is applied to all types of geologic processes. ... The other big idea inherent in uniformitarianism is that Earth is a very old place.

Question
what happens to the gravitational force when the distance between them stays the same and the mass of both objects is doubled
Solution 1

The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.

Question
A dog chases a car, running 825 m west in 6.22 s. What is the average velocity of the dog?
Solution 1

132.64m/s

Explanation:

Averagevelocity= distance/time

From the question, the distance d = 825m

time t = 6.22 secs

Using the above formula

We have

average velocity = 825/6.22

= 132.64m/s

Question
A sprinter, running a 100-meter race, can accelerate with a constant acceleration for 4.10 s before reaching his top speed. He can then can maintain that speed for the rest of the race. He runs the 100 meters in 10.0 s. What is the runner's speed as he crosses the finish line?
Solution 1

=12.579m/s

Explanation:

with constant acceleration the displacement is calculated as follows

Δx=(+)t/2

for the first 4.10s the is the top speed so, and, for the other  5.9s, the speed is constant with value ,  so:

100 m =*(10-4.1s)+ (0+)4.1s/2

so =100/(5.9+2.05)=12.579m/s

Solution 2

12.579m/s:with constant acceleration the displacement is calculated as follows Δx=(+)t/2for the first 4.10s the  is the top speed so, and, for the other  5.9s, the speed is constant with value ,  so:100 m =*(10-4.1s)+ (0+)4.1s/2so =100/(5.9+2.05)=12.579m/s
