The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.
A. The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.
B. The gravitational potential energy decreases and the kinetic energy increases.As soon as the ball starts moving it no longer has gravitational potential energy; it has only kinetic energy.
C. The kinetic energy and and gravitational potential energy both decrease. Both forms of energy are used up as the ball moves and are not transformed into any other form of energy.
D. The gravitational potential energy and the kinetic energy both stay the same. One form of energy cannot be transformed into a different form of energy.
Answers
Answer:
The gravitational potential energy decreases and the kinetic energy increases. The gravitational potential energy is transformed into kinetic energy as the ball rolls down the ramp.
Explanation:
The gravitational potential energy is the energy due to the position of a body above the ground.
Kinetic energy is the energy due to the motion of a body.
From the law of conservation of energy "energy is neither created nor destroyed but transformed from one form to another".
As the ball rolls down the ramp, the potential energy at the height is converted to kinetic energy.

Ranjana has average velocity 3.2 m/s
How long does she take to cover a displacement
of 256 m
Answers
Answer:
t= 80 seonds
Explanation:
Given that,
The average velocity of Ranjana, v = 3.2 m/s
We need to find how long does she take to cover a displacement of 256 m. Let she takes t time.
We know that,
Average speed = distance/time
So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{256\ m}{3.2\ m/s}\\\\t=80\ s[/tex]
So, she will take 80 seconds to cover a displacement of 256 m.

Solution
Newton's Gravity Law:
[tex]\rm F=G.\dfrac{m_1.m_2}{r^2}[/tex]
with F = gravitational force,
G = gravitational constant,
m1, m2 = mass of object,
r = distance between two objects.
Input the value :
F = (6.67.10⁻¹¹N.m² / kg² x 1500²) : 50²
F = 6.0 x 10⁻⁸ N

An eagle flying 10 meters per second swoops down to the ground to catch a snake speed velocity or acceleration
Answers
Answer:
Velocity because it has both magnitude (10m/s) and direction (to the ground).
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
[tex]Velocity = \frac{distance}{time}[/tex]
In this scenario, an eagle flying 10 meters per second swoops down to the ground to catch a snake. Therefore, this is an example of velocity.
A meterologist made these observations one day:
• In the morning, anocean wave hit a shoreline every 15 seconds.
• In the afternoon, an ocean wave hit the shorlinie every 30 seconds.
Identify whether the ocean waves transferred more or less energy in the morning than in the afternoon.
Write your answer in complete sentences.
Answers
Answer:
They transfered more energy in the morning.
Explanation:
This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with the waves. They have more energy, so they can crash aganst the shore more!

A train moves at 300 km/h. How far will it go in 5 hours?
Answers
Answer:
1,500 km
Explanation:
300 km/h
300 kilometers PER HOUR
So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.
300 * 5 = 1,500
The train moves at 1,500 km in 5 hours.

what is the formula for acceleration?
Answers
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
