How do elastic energy, kinetic energy, and gravitational energy differ from each other?
Answer:
Gravitational pulls things to the ground
Elastic is stretched or compressed or a shape or object
Kinetic is kinda like the force of motion
Hope this helps
In the gravitational energy, things are pulled to the ground by gravity, for elastic energy stretched, squeezed, or as a shape or item, and for kinetic energy it is similar to the force of motion.
What is Kinetic energy?Kinetic energy is the term used in mechanics to describe the impulse that an object experiences as it moves. It is described as the amount of effort needed to move someone of a certain mass to rest to a given velocity. Except for fluctuations in speed, the body retains its acceleration after receiving it during acceleration.
The body uses the same lot of fuel when slowing down from its current rate to a state of rest. Formally, kinetic energy refers to any element in the Lagrangian of such a system that seems to have a derivative with respect to time.

The [ Select ] the distance between the effort force and the fulcrum of a lever, the [ Select ] force is needed to complete the work. The [ Select ] the distance between the effort force and the fulcrum of a lever, the [ Select ] the mechanical advantage, making the work easier.
Answer:
Answer in explanation
Explanation:
What we want to do here is to basically put in words in the select pane that could actually beat complete the question.
The higher the distance between the effort and the function of a lever, the higher the force needed to complete the work.
The smaller the distance between the effort force and the fulcrum of a lever, the smaller the mechanical advantage , making the work easier
A cyclist rides at a velocity if 12m/s.if the cyclist deceleates a rate of 1.5m/s.how long will take her to reach a velocity of 3m/s?
1)identify your variables -what is what ?
2)pick your equation
3)plug in and solve
Answer:
t=6s
Explanation:
v=3m/s
u=12m/s
a=-1.5ms-²
t=?
v=u+at
3=12+(-1.5)t
3-12=-1.5t

A car accelerates from 1.5 to 18 m/sec in 9.6 seconds. Calculate its acceleration. and the other one is During a race, you speed up from 2.2 m/sec to 4 m/sec in 3.2 seconds. (a) What is your change in speed? ____ m/sec (b) What is your acceleration? ___ m/sec2
Answer:
(1) The acceleration is 1.72 m/s²
(2) (a) The change in speed is 1.8 m/s
(2) (b) The acceleration is 0.563 m/s²
Explanation:
(1)
Given;
initial velocity, u = 1.5 m/s
final velocity, v = 18 m/s
time of motion, t = 9.6 s
The acceleration is given by;
a = (v - u) / t
a = (18 - 1.5) / 9.6
a = 1.72 m/s²
(2)
Given;
initial speed, u = 2.2 m/s
final speed, v = 4 m/s
time of motion, t = 3.2 s
(a) The change in speed is given by;
Δv = v - u
Δv = 4 m/s - 2.2 m/s
Δv = 1.8 m/s
(b) the acceleration is given by;
a = Δv / t
a = 1.8 / 3.2
a = 0.563 m/s²

A skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s2. If
the skier covers the course in 10 sec, how fast was he moving at the bottom of the course?
O31 m
O 13 m/s
O-29 m/s
O 31 m/s
If a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s², then he was moving at 31 m / s at the bottom of the course.
What are the three equations of motion?There are three equations of motion given by Newton
v = u + at
S = ut + 1/2 × a × t²
v² - u² = 2 × a × s
As given in the problem, a skier (down a straight course) is able to enter the starting gate with a speed of 1 m/sec and the average acceleration down the hill was 3 m/s² .
By using the first equation of the motion,
v = u + at
v = 1 + 3 × 10
v = 31 m / s
Thus, he was moving at 31 m / s at the bottom of the course.

A jet airliner moving initially at 538 mph (with respect to the ground) to the east moves into a region where the wind is blowing at 937 mph in a direction 23 degrees north of east. What is the new speed of the aircraft with respect to the ground. Answer in units of mph
Answer:
The speed is "1447.576 mph".
Explanation:
The given values are:
Direction (north to east)
= 23°
Wind's speed
= 937 mph
Jet moving at a speed
= 538 mph
Now,
The velocity of jet airliner with respect to the ground will be:
⇒ [tex]v=v_{1}+v_{2}[/tex]
⇒ [tex]v=\sqrt{(538)^2+(987)^2+2(538)(937)\times Cos23^{\circ}}[/tex]
⇒ [tex]=1447.576 \ mph[/tex]
A skydiver jumps from an airplane traveling 120. km/hr at a height of 1000. m. If his parachute must open 500. m above the ground, how long does he have for the chute to open?
Answer:
The parachute to open in 15 sec.
Explanation:
Given that,
Velocity = 120 km/hr
Height = 1000 m
If his parachute must open 500. m above the ground.
We need to calculate the time for parachute to open
Using formula of time
[tex]v=\dfrac{d}{t}[/tex]
[tex]t=\dfrac{d}{v}[/tex]
Where, d = distance
t = time
v = velocity
Put the value into the formula
[tex]t=\dfrac{500}{120\times\dfrac{5}{18}}[/tex]
[tex]t=15\ sec[/tex]
Hence, The parachute will be open in 15 sec.

B. is the correct answer just took the topic review.
Explanation:
Edge2020. Hope that this helps! Peace and Love
Courts often depend upon recovered memories is the wrong statement about the hypnotic regression.
What is hypnotic regression?Hypnotic regression is a contentious method because it can have a number of negative effects on the subjects who undergo it. For the beginners, the memories recovered through any regression can be doubtful and not trust-worthy. All the suggestions or leading questions from the hypnotist or other people of witnesses can affect the memory.
The previous lives memories will be found by the hypnotic technique as a past life regression. If they used to remember the past life by this method they have high chance of getting into the traumas.
Regression therapy mostly used to identify the cause of your current thoughts and reactions. Therapists who is using this techniques to access subconscious memories that are guiding your current behaviour.
Regression therapy is a method of treatment that could approach and focuses on resolving particular past events that are thought to be interfering or relatable with a person's current mental and emotional well-being.
