A Force Of 15 N Is Applied To A Spring, Causing It To Stretch 0.3 M. What Is The Spring Constant For The Particular Spring

1 answer:

3 0

The spring constant is the number of Newtons needed to cause an extension of 1metre. So in this case it is 15/0.3 = 50 N/m

An Indy 500 race car's velocity increases from 4.0 m/s to +36

Soloha48 [4]

Answer:

The average acceleration is $8\ m/s^2$

Explanation:

Uniform Acceleration

When an object varies its velocity at the same rate, the acceleration is constant.

The relation between the initial and final speeds is:

$v_f=v_o+a.t$

Where:

vf = Final speed

vo = Initial speed

a = Constant acceleration

t = Elapsed time

The acceleration can be calculated by solving for a:

$\displaystyle a=\frac{v_f-v_o}{t}$

The Indy 500 race car increases its speed from vo=4 m/s to vf=36 m/s in t=4 s. Thus, the average acceleration is:

$\displaystyle a=\frac{36-4}{4}=8\ m/s^2$

The average acceleration is $8\ m/s^2$

Two containers hold equal masses of nitrogen gas at equal temperatures. You supply 10 J of heat to container A while not allowin

telo118 [61]

Answer:

TA is greater than TB

$T_{A}$ > $T_{B}$

Explanation:

Specific heat at constant pressure $C_{p}$ is greater than specific heat at constant volume $C_{v}$ .Therefore for given amount of supplied heat,increase in temperature at constant volume is greater than increase in temperature at constant pressure

Hence

TA is greater than TB

$T_{A}$ > $T_{B}$

A neutral metal sphere is attracted to a positively-charged amber rod. Why does this occur?.

aniked [119]

Hi there!

A neutral metal sphere is comprised of both ELECTRONS and PROTONS.

Recall that electrons have a NEGATIVE (-) charge, and protons have a POSITIVE (+) charge.

Opposite charges attract, and like charges repel.

In this instance, the positively-charged rod will cause the electrons in the neutral metal sphere to move towards the side facing the rod (opposite charges attract), which causes the two to be attracted to one another.
