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.

Which of the following is an effect of the electric force?
stich3 [128]

As we know that two charges exert force on each other when they are placed near to each other

The force between two charges is given as

F = \frac{kq_1q_2}{r^2}

here we know that

q_1, q_2 = two different point charges

r = distance between two point charges

also we know that two similar charges always repel each other while two opposite charges always attract each other

so here correct answer would be

<em>A. A positive and negative charge attract each other.</em>

(a) At what height above Earth’s surface is the energy required to lift a satellite to that height equal to the kinetic energy r
Nikitich [7]

Answer:

Explanation:

Gravitational Potential Energy at earth surface U_1=\frac{GM_em}{R_e}

Gravitational Potential Energy at height h is U_2=\frac{GM_em}{R_e+h}

Energy required to lift the satellite E_1=U_1-U_2

E_1=\frac{GM_em}{R_e}-\frac{GM_em}{R_e+h}

Now Energy required to orbit around the earth

E_2=\frac{1}{2}mv_{orbit}^2=\frac{GM_2m}{2(R_e+h)}

\Delta E=E_1-E_2

\Delta E=\frac{GM_em}{R_e}-\frac{GM_em}{R_e+h}-\frac{GM_2m}{2(R_e+h)}

E_1=E_2  (given)

\frac{GM_em}{R_e}-\frac{GM_em}{R_e+h}-\frac{GM_2m}{2(R_e+h)}=0

\frac{1}{R_e}-\frac{3}{2(R_e+h)}=0

h=\frac{R_e}{2}

h=3.19\times 10^6\ m

(b)For greater height E_1  is greater than E_2

thus energy to lift the satellite is more than orbiting around earth

A length of wire is cut into five equal pieces. the five pieces are then connected in parallel, with the resulting resistance be
ycow [4]
The equivalent resistance of resistors connected in parallel is
\frac{1}{R_{eq}} = \frac{1}{R_1} +  \frac{1}{R_2} + ...
In our problem, we have 5 identical resistor of resistance R, so their equivalent resistance is
\frac{1}{R_{eq}} =  5 (\frac{1}{R} )
The problem also says that the equivalent resistance is R_{eq}= 17 \Omega, so we can find the resistance R of each piece of wire:
R=5 R_{eq} = 5 \cdot 17 \Omega = 85 \Omega

In the initial wire, it's like the 5 pieces are connected in series, so the equivalent resistance of the wire is just the sum of the resistances of the 5 pieces:
R_{wire} = 5 R = 5 \cdot 85 \Omega = 425 \Omega
