How much displacement will a spring with a constant of 120N / m achieve if it is stretched by a force of 60N?
Andrew [12]

Answer:

Explanation:

There's a formula for this:

F = k*displacement

F being force, k being the spring constant, and displacement being the change in x

We are given the force and the spring constant, so this is essentially isolating the Δx term. Do 60N/120N per meter. The newtons cancel out and you get a final answer of Δx = 0.5 meters

If Mrs. Reichelt throws a chromebook, because it won't login correctly, with a force of 8N, and the chromebook accelerates at 5m
suter [353]

Answer:

1.6 kg

Step-by-step Solution:

Since Force = mass × acceleration we have:

F = 8N

a= 5 m/s^2

m = ?

By plugging the values above into F=ma we obtain:

F=ma\\\\8=m(5)\\\\\frac{8}{5}=\frac{m(5)}{5}\\\\m=\frac{8}{5}=1.6

Therefore, the Chromebook has a mass of 1.6 kilograms.

A battery derives electric energy from _____energy?
sammy [17]
A). nuclear
No.  There were batteries long long before we learned
how to use nuclear energy.  Also, there is no danger of
exposure to radioactivity when you're working with a battery.

b). mechanical
No.  A battery has no moving parts.

c). gravitational
No.  No matter how high you take a battery in an airplane, or
how far you lower it into a mine-shaft, its characteristics don't
change.  In fact, batteries even work on things that are in orbit.

d). chemical
Bingo.
