Gravitational potential energy=mass of object x gravitational field strength on earth(9.8 usually rounded to 10) x the height the object is held at

Therefore if two objects were held at the same height, the object with more mass(the heavier object) will fall faster because it's gravitational potential energy is greater than that of the lighter object

What is the function of the small circular black plastic at the bottom of the light
Flauer [41]

Answer:

These low-pressure gases prevent the filament inside the bulb from burning out; it also relieves some of the stress on the glass globe from normal atmospheric pressure, lessening the chance of glass breakage.

The force between a 100 kg man and the Earth is 980 N. How close must two protons (1.6 X 10-19 C) be to generate the same force?
LUCKY_DIMON [66]

The distance between two protons to generate 950N of force is 0.49 X 10⁻¹⁵ m

<u>Explanation:</u>

Given:

Mass of man, m = 100 kg

Force between man and earth = 980 N

Charge of proton, q = 1.6 X 10⁻¹⁹C

Same force is generated between them

Distance between two protons, r = ?

According to Coulomb's law:

F = k\frac{q_1q_2}{r^2}

where,

k is Coulomb's constant

k = 9 X 10⁹ Nm²/C²

According to the question:

950 = k\frac{q_1q_2}{r^2}

Solving the equation:

950  = (9X10^9) X\frac{(1.6 X 10^-^1^9 X 1.6 X 10^-^1^9)}{r^2} \\\\r^2 = \frac{(9 X 10^9) (1.6 X 10^-^1^9 X 1.6 X 10^-^1^9)}{950} \\\\r^2 = 0.024 X 10^-^2^9\\\\r^2 = 0.24 X 10^-^3^0\\\\r = 0.49 X 10^-^1^5 m

Therefore, the distance between two protons to generate 950N of force is 0.49 X 10⁻¹⁵ m

A mass m = 1.1 kg hangs at the end of a vertical spring whose top end is fixed to the ceiling. The spring has spring constant k
adell [148]

Answer:

a) = 10.22 rad/s

b) = 0.35 m

Explanation:

Given

Mass of the particle, m = 1.1 kg

Force constant of the spring, k = 115 N/m

Distance at which the mass is released, d = 0.35 m

According to the differential equation of s Simple Harmonic Motion,

ω² = k / m, where

ω = angular frequency in rad/s

k = force constant in N/m

m = mass in kg

So,

ω² = 115 / 1.1

ω² = 104.55

ω = √104.55

ω = 10.22 rad/s

If y(0) = -0.35 m and we want our A to be positive, then suffice to say,

The value of coefficient A in meters is 0.35 m
