A spring (k = 20 N/m) sits on a frictionless surface. The spring is compressed 20 cm and a 2 kg mass is placed before the spring

Olenka [21]

Answer:

E.)none of the above

Explanation:

Elastic energy = kinetic energy

½ kx² = ½ mv²

v = x √(k / m)

v = 0.2 m √(20 N/m / 2 kg)

v = 0.632 m/s

Time to travel 2.0 m:

t = (2.0 m) / (0.632 m/s)

t = 3.16 s

Krishne wants to measure the mass and volume of a key. Which tools should she use? a balance and a beaker of water a balance and

Ratling [72]

Balance and beaker of water. The balance will measure mass and the beaker will measure the volume when you take the initial volume without the key subtracting that value from the value with the key in the beaker

A horizontal force of 300 N is applied to move a 55 kg sofa across a 10 m level surface. What is the net work done by this 300 N

gavmur [86]

I think the answer is 3000 joules since work is force times distance.

Answer:

the time period is 22.63 years

Explanation:

The computation of the number of years taken is as follows:

According to the Keplers law

$T^2 \propto R^3$

Here T denotes the time period

And, R denotes the average distance among the sun and planet

Now let us assume for earth

R_1 & T_1 be 1 year

So, for Planet

$R_2 = 8R_1 , T_2 = ?$

Now applied Keplers law

$(\frac{T_2}{T_1})^2 \propto (\frac{R_2}{R_1})^3\\\\(T_2)^2 = (\frac{8R_1}{R_1})^3 \times 1^2\\\\(T_2)^2 = 512\\\\T_2 = 22.674$

So, the time period is 22.63 years
