Energy that is stored is kinetic energy

Physics

That statement is false. Stored energy is potential energy. Kinetic is a word that refers to motion. Kinetic energy is the energy of motion not stored energy.

The car has a constant deceleration of 4.20 m/s^2. If its initial velocity was 24.0 m/s, how long does it take to come to a stop
nalin [4]

Answer:

The time is 5.71 sec.

Explanation:

Given that,

Acceleration a= -4.20 m/s^2

Initial velocity = 24.0 m/s

We need to calculate the time

Using equation of motion

v = u+at[/tex]

Where, v = final velocity

u = inital velocity

t = time

a = acceleration

Put the value into the formula

0 =24.0 +(-4.20)\times t

t = \dfrac{-24.0}{-4.20}

t=5.71\ sec

Hence, The time is 5.71 sec.

What type of equilibrium is guaranteed by each condition of equilibrium
Ostrovityanka [42]

Answer: Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium

Explanation: Hope this helped

The AM radio station WDRJ broadcasts news and sports at a frequency of 704 kHz (kilohertz). What is the wavelength of the radio
Doss [256]

Answer:

AM broadcasts occur on North American airwaves in the medium wave frequency range of 525 to 1705 kHz (known as the “standard broadcast band”). The band was expanded in the 1990s by adding nine channels from 1605 to 1705 kHz.

a baseball is thrown vertically upwards and returns to the thrower three seconds later find speed at which the ball us thrown​
rodikova [14]

Answer:

14.7 m/s

Explanation:

Since the motion of the ball is a uniformly accelerated motion, we can find the initial speed by using the following suvat equation:

s=ut+\frac{1}{2}at^2

where

s is the vertical displacement

u is the initial velocity

t is the time

a is the acceleration

In this problem, we have:

s = 0 (because at the end of the motion, the ball returns to its original position)

u = ?

a=g=-9.8 m/s^2 is the acceleration of gravity (negative because it is downward)

t = 3 s is the total time of flight

Solving for u, we find the initial velocity of the ball:

0=ut+\frac{1}{2}at^2\\u=-\frac{1}{2}at=-\frac{1}{2}(-9.8)(3)=14.7 m/s

Why should you choose why should you choose wire with a thinner insulation?
irakobra [83]
