Answer:
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.

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.

Answer:
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:
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.

Answer:
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.
Explanation:
The present is the key to the past. He called this the principle of uniformitarianism. It is that if we can understand a geological process now and we find evidence of that same process in the past, then we can assume that the process operated the same way in the past.

Answer:
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.

Answer: Internal energy changes that do not register on a thermometer are due to changes in the potential energy of the particles.
Explanation: a thermometer measures the temperature, which is a measure of the average kinetic energy of the particles.
Answer:
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
Answer:
=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
, Â so:
100 m =*(10-4.1s)+ (0+
)4.1s/2
so =100/(5.9+2.05)=12.579m/s
