The electrostatic force between two charges located 2 meters apart is 0.10 N. What will the force be between these charges when

Vikentia [17]

Given that 2 m is to .10N

we will set up a ratio & proportion

.10 x
— —
2 1

cross multiply

2x = .10(1)

divide both sides by 2

x (and the answer) = .05 N

The force of gravity acting<br> on a child's mass on earth is 490 newtons. what's the child's mass?

UNO [17]

F = m • a

What we know:
- Gravity: 9.8 m/s
- Force: 490 N

Equation derived:
m = F/a
m = 490/9.8
= 50 kg

Answer:

Teh velocity of ball with respect to the ground is 29.2 m/s.

Explanation:

Velocity of car, vc = 25 due m/s east

velocity of ball with respect to car, v(b,c) = 15 m/s due Z axis

Write the velocities in the vector form

$\overrightarrow{v}_{c}=25 \widehat{i}\\\\\overrightarrow{v}_{(b,c)}=15 \widehat{k}$

The velocity of ball with respect to ground is

$\overrightarrow{v}_{(b,c)}= \overrightarrow{v}_{(b,g)}-\overrightarrow{v}_{(c,g)}\\\\15 \widehat{k} = \overrightarrow{v}_{(b,g)} - 25 \widehat{i}\\\\\overrightarrow{v}_{(b,g)} = 25 \widehat{i} + 15 \widehat{k}\\\\v_{(b,g)}=\sqrt{25^2 + 15^2}=29.2 m/s$
