The statement 'energy cannot be created or destroyed' BEST supports the idea that energy remains constant during an energy transformation. It is the first law of thermodynamics.

<h3>Law of Conservation of Energy</h3>

The law of conservation of energy, also known as the first law of thermodynamics, indicates that energy can neither be created nor destroyed.

According to this law, the energy can be interchanged from one type of energy (e.g., kinetic energy) form to another (e.g., potential energy).

The first law of thermodynamics is fundamental for understanding major science disciplines, and it is a rosetta stone in physics.

Write a responding to the prompt.<br><br><br><br>What role does mass play in gravitational forces
suter [353]
Gravity is the attraction between two objects that have mass. The amount of gravity is directly proportional to the amount of mass of the objects and inversely proportional to the square of the distance between the objects. Gravity is a force that increases the velocity of falling objects - they accelerate.

A 1200 Kg car rounds a corner of radius r = 45m. If the coefficient of static friction between the ties and the road is us = 0.8
Vaselesa [24]

Answer:

The greatest speed of the car is 19.36m/s

Explanation:

The maximum speed the car will attain without skidding is given by:

F= uN = umg ...eq1

But F = mv^2/r

mv^2/r = umg

Dividing both sides by m, leaves you with:

V= Sqrt(ugr)

Where u = coefficient of static friction

g = acceleration due to gravity

r = raduis

Given:

U = 0.82

r=0.82

g= 9.8m/s

V = Sqrt(0.82 × 9.8 × 45)

V = Sqrt(374.85)

V = 19.36m/s

A diver is on a board 3.00 m above the water . She jumps straight up at 3.25 m/s. . How many seconds later does she hit the wate
zzz [600]

Answer:

1.18 sec

Explanation:

v = 0

u = 3.25m/s

v = u - gt

t1 = u/g = 3.25/9.8 = 0.332 s

height above board = v²/2g =

3.25²/(2×9.8) = 0.54 m

time to fall from there to water

t2 = √(2h/g) = √(2(3+ 0.54)/9.8) = 0.85 s

total time = t1 + t2

total time = 0.85 + 0.332 = 1.182 s
