Mr. Voytko wants to know how high in meters he can lift an 0.3 kg apple with 7.35 joules?

Physics

ivolga24 [154]3 years ago
8 0

Answer:

the height above the ground through Mr. Voytko lifted the apple is 2.5 m.

Explanation:

Given;

energy of Mr. Voytko, E = 7.35 J

mass of the apple, m = 0.3 kg

Apply the principle of conservation of energy.

Energy of Mr. Voytko = Potential energy of the apple due to its height above the ground.

E = mgh

where;

h is the height above the ground through Mr. Voytko lifted the apple.

g is acceleration due to gravity = 9.8 m/s²

h = E / (mg)

h = 7.35 / (0.3 x 9.8)

h = 2.5 m

Therefore, the height above the ground through Mr. Voytko lifted the apple is 2.5 m.

Yellow light travels through a certain glass block at a speed of 1.97 × 108 m/s. The wavelength of the light in this particular
Andre45 [30]

The frequency of the yellow light is 5.17\cdot 10^{14}Hz

Explanation:

The relationship between wavelength, frequency and speed of a wave is given by the wave equation:

v = f \lambda

where

v is the speed of the wave

f is the frequency

\lambda is the wavelength

For the yellow light in this problem, we have:

v=1.97\cdot 10^8 m/s is the speed

\lambda=3.81\cdot 10^{-7} m is the wavelength

Solving for f, we find its frequency:

f=\frac{v}{\lambda}=\frac{1.97\cdot 10^8}{3.81\cdot 10^{-7}}=5.17\cdot 10^{14}Hz

Identify the equation used to calculate the perpendicular force (F⊥) acting on a block on an inclined plane.
pychu [463]
Using geometrical arguments, we can see that the angle of the inclined plane \theta is equal to the angle between Fg and the perpendicular force.

But the perpendicular force is the projection of Fg along the perpendicular axis, and Fg=mg, so the correct answer is

grigory [225]
<span>The answer is transformer. They utilize electromagnetic induction to generate current. This is only possible in alternating current due to the differential increase and decrease of electrical current that induces changes in magnetic flux in the coil. This varies the magnetic flux of the primary coil that generates current in the secondary coil.</span>

A suitcase is pulled 28 feet along a flat sidewalk with a constant upward force of 80 lb at an angle of 23degrees with the horiz
Elenna [48]

Answer:

2795.3 J

Explanation:

distance, d = 28 feet = 8.53 m

Force, F = 80 lb = 356 N

Angle, θ = 23°

Work = F x d x cos θ

W = 356 x 8.53 x cos 23

W = 2795.3 J

Thus, the work done is 2795.3 J.
