The historical method includes what steps?
It just completely stops kinetic energy is movement so technically it would stop.
Answer:
Explanation:
Formula and givens
- λ = c / f
- λ is the wavelength
- c = the speed of light
- f = the frequency
- c = 3*10^8
- f = 7.89 * 10^14
λ = ?
Solution
λ = 3*10^8 / 7.89*10^14
λ = 3*10^8/7.89*10^14
λ = 2.36 * 10^7
λ = 236 nanometers. What you use as your solution depends on what what you have been taught.
Answer:
The maximum load that this person is able to lift is 34.3 N
Explanation:
Applying the balancing torque, the expression is equal:
F₁L₁ = F₂L₂
Where
g = 9.8 m/s² = gravity
L₁ = 0.8 m
F₂ = 527 N
L₂ = 6 - 0.8 = 5.2 m
Replacing and clearing the mass m:
The maximum load that this person is able to lift is:
F = m * g = 3.5 * 9.8 = 34.3 N
Let us consider the tension produced on both the sides of the rope is T.
We have been given that the rope is mass less and the rope is passing through a pulley which is stationary.
The body is moving downward with an acceleration of
As the rope is the same one which is passing over a mass less pulley and connected by two masses,hence, acceleration of each block will be the same in magnitude.
Here the tension is acting in vertical upward direction and the weight is acting in vertical downward direction. Here,the body is moving in vertical upward direction. Hence, the net force acting on it is-
[1]
Here the tension is acting in vertical upward direction while weight is in vertical downward direction. The body is moving in downward direction. Hence the net force acting on it will be-

Combing 1 and 2 we get-
