A spring with k = 83 N????m hangs vertically next to a ruler. The end of the spring is next to the 15-cm mark on the ruler. If a

2.5-kg mass is now attached to the end of the spring, and the mass is allowed to fall, where will the end of the spring line up with the ruler marks when the mass is at its lowest position?

Answer:

0.4452m

Explanation:

Spring constant is given as:

k=F/x

But F is mass times velocity(gravitational acceleration(=9.8m/s^2)

83N/m=2.5kg(9.8m/s^2)/x

x=0.2952m

Therefore the ruler reading will be x+0.15m. Hence the ruler reading is 0.4451m

Given the Earth's density as 5.5 g/cm3 and the Moon's density as 3.34 g/cm3, determine the Roche limit for the Moon orbiting the
Assoli18 [71]

Answer:

The Roche limit for the Moon orbiting the Earth is 2.86 times radius of Earth

Explanation:

The nearest distance between the planet and its satellite at where the planets gravitational pull does not torn apart the planets satellite is known as Roche limit.

The relation to determine Roche limit is:

Roche\ limit=2.423\times R_{P}\times\sqrt[3]{\frac{D_{P} }{D_{M} } }     ....(1)

Here R_{P} is radius of planet and D_{P}\ and\ D_{M} are density of planet and moon respectively.

According to the problem,

Density of Earth,D_{P} = 5.5 g/cm³

Density of Moon,D_{M} = 3.34 g/cm³

Consider R_{E} be the radius of the Earth.

Substitute the suitable values in the equation (1).

Roche\ limit=2.423\times R_{E}\times\sqrt[3]{\frac{5.5 }{3.34 } }

Roche\ limit= 2.86R_{P}

a cepheid variable star is a star whose brightness alternately increases and decreases. suppose that cephei joe is a star for wh
MrRissso [65]

After one day, the rate of increase in Delta Cephei's brightness is;0.46

We are informed that the function has been used to model the brightness of the star known as Delta Cephei at time t, where t is expressed in days;

B(t)=4.0+3.5 sin(2πt/5.4)

Simply said, in order to determine the rate of increase, we must determine the derivative of the function that provides

B'(t)=(2π/5.4)×0.35 cos(2πt/5.4)

Currently, at t = 1, we have;

B'(1)=(2π/5.4)×0.35 cos(2π*1/5.4)

Now that the angle in the bracket is expressed in radians, we can use a radians calculator to determine its cosine, giving us the following results:

B'(1)=(2π/5.4)×0.3961

B'(1)≈0.46

If you are given time and distance, you can determine power if you know force. watts. energy. joules.
DENIUS [597]
If you are given time and distance, you can determine power if you know force. watts. energy. joules.

Answer is joules.     

Power is defined as the rate of doing work. Hence power = work / time then you obtain watts. Work is the product of force and displacement (distance). Hence in formula, w = F x s. In which the S.I unit of work is joule in the product. This is what you have to obtain in order to calculate for power.
