Answer:
q = 8.85 x 10⁻¹¹ C
Explanation:
given,
Electric field, E = 1.18 N/C
distance, r = 0.822 m
Charge magnitude = ?
using formula of electric field.

k is the coulomb constant


q = 8.85 x 10⁻¹¹ C
The magnitude of charge is equal to q = 8.85 x 10⁻¹¹ C
Answer:
20 metres
Explanation:
Given that the area of a triangle is 30 square metres (m²). Using the equation A = 1/2bh, this is the formula for the triangle.
where b is base and h is height
Given that b = 3 metres.
To calculate h, Substitute b and A into the equation
30 = 1/2 × 3 × h
3h = 60
h = 60/3
h = 20 m
Therefore, h is equal to 20 metres
A 13-kg sled is moving at a speed of 3.0 m/s. At which of the following speed will the sled have twice as much kinetic energy?
<span>4.2 m/s</span>
F = M A
Force = (mass) x (acceleration)
= (1,650 kg) (4 m/s²) = 6,600 kg-m/s² = <em>6,600 Newtons</em>
