Answer:
B would be the correct answer
Answer:
because you can get very electrocuted and you could get a disease I never put your hand add water on and touching water cuz you can get your hand electrocuted
Explanation:
Ek = 1/2 mv^2
9 × 10^4 = 1/2 × 800 × v^2
9 × 10^4/400 = 400 v^2 / 400
9 × 10^4/400 = v^2
√225 = v
15 ms⁻¹ = v
That's the only way I know how to work it out
I think in this case velocity and speed would be considered the same because me
s = d/t and v=d/t
one is distance travelled and the other is displacement of a body
Jennifer is able to drag her brother out of the zoo due to an applied net force of 15 N.
<h3>What is force?</h3>
Force refers to any agent which tends to cause a change in the motion or state of an object.
Forces are of two types;
- contact forces, and
- Non-contact forces
The net force is the difference between two forces which causes a change in the motion of an object.
The net force that Jennifer applies = 35 N - 20 N = 15 N
Therefore, Jennifer is able to drag her brother out of the zoo due to an applied net force of 15 N.
