Answer:

b. Gravity is the weaker force; it is related to mass.

Explanation:

Gravity is the force of gravitational attraction of earth on all objects near its surface

This force on all objects depends on the mass of the objects

This force is given by

F = \frac{GMm}{r^2}

F = mg

so here it is a weak force as it depends on mass and acceleration due to gravity while strong nuclear force is independent of mass and it only depends on the distance between the nuclei.

So as we will change the distance between the nuclei the force between them will change

So here correct answer is

b. Gravity is the weaker force; it is related to mass.

Haley is trying to pull an object upward. The below forces are acting on the object.
ra1l [238]

For this case, the first thing we must do is define a reference system.

Suppose that the positive direction of the reference system is upward.

We have that the sum of forces in the vertical axis is given by:

Fy = Fp - Fg

Substituting values:

Fy = 5500 - 6000

Fy = - 500

The negative sign means that the direction of the force with respect to the defined coordinate system is downward.

Answer:

The net force is:

↓ 500N

m = 43.2 kg

Explanation:

volume of sphere = (4/3)pi(r)^3

= (4/3)(3.14)(2 m)^3

= 33.5 m^3

density = mass/volume

or solving for mass m,

m = (density)×(volume)

= (1.29 kg/m^3)(33.5 m^3)

= 43.2 kg

The filament of a certain lamp has a resistance that increases linearly with temperature. When a constant voltage is switched on
Neporo4naja [7]

Answer:

162.8 K

Explanation:

initial current = io

final current, i = io/8

Let the potential difference is V.

coefficient of resistivity, α = 43 x 10^-3 /K

Let the resistance is R and the final resistance is Ro.

The resistance varies with temperature

R = Ro ( 1 + α ΔT)

V/i = V/io (1 + α ΔT )

8 = 1 + 43 x 10^-3 x ΔT

7 = 43 x 10^-3 x ΔT

ΔT = 162.8 K

Thus, the rise in temperature is 162.8 K.

KIIS FM broadcasts at 102.7 MHz, what is the wavelength of that radio wave?
marysya [2.9K]

Answer:

2.92 m

Explanation:

As we know, frequency × Wavelength = Speed of light

so here frequency of 102.7 MHz can be written as 102.7× 10⁶ Hz..

So Lambda (wavelength) = 3×10⁸/ 102.7 × 10⁶ which gives 2.92 metres or 2.92 × 10¹⁰ Å
