Answer : The force needed is 108 N.

Explanation :

Force : It is defined as the product of mass of an object and acceleration of an object.

Formula used :

Force=Mass\times Acceleration

Given:

Acceleration = 1.2m/s^2

Mass = 90 kg

Now put all the given values in this formula, we get:

Force=90kg\times 1.2m/s^2

Force=108kg.m/s^2=108N

The unit of force is, N or kg.m/s^2

Therefore, the force needed is 108 N.

∑F = ma = (90 kg)(1.2 m/s²) = 108 N = 100 N (1 significant digit)

aliina [53]

Answer:

Explanation:

we have to make charge inside the conductor zero because we know that electric field inside the conductor should be zero

so,  the outer surface of the conductor should contain + 10 uC of charge and the inner surface contains -10 uC

Flura [38]
The presence of helium gas indicates the radioactive sample is most likely decaying by α-decay, or alpha decay. α-decay is the type of radioactive decay in which an atomic nucleus emits α particles. α particles are Helium nuclei. So the correct answer would be α-decay.

When the distance between two charges is halved, the electrical force between them?
Llana [10]
If the distance between two charges is halved, the electrical force between them increases by a factor 4.

In fact, the magnitude of the electric force between two charges is given by:
F= k \frac{q_1 q_2}{r^2}
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two charges

We see that the magnitude of the force F is inversely proportional to the square of the distance r. Therefore, if the radius is halved:
r'= \frac{r}{2}
the magnitude of the force changes as follows:
F'=k \frac{q_1 q_2}{r'^2}=k \frac{q_1 q_2}{( \frac{r}{2})^2 }=k \frac{q_1 q_2}{ \frac{r^2}{4} } =4k  \frac{q_1 q_2}{r^2}=4 F
so, the force increases by a factor 4.
