Answer:

<h3>2479 Newton</h3>

Solution,

Mass=100 kg

Acceleration due to gravity(g)=24.79 m/s^2

Now,.

 $weight = m \times g \\ \: \: \: \: \: \: \: \: \: \: = 100 \times 24.79 \\ \: \: \: \: \: \: = 2479 \: newton$ 

hope this helps ..

Good luck on your assignment..

Q = mL

We need to know the latent heat of fusion, L, for 0 degrees.

L = 336 kJ/kg, m = 2kg

where L is the latent heat for vaporization

Q = 2 * 336 = 672 kJ

For conversion between 0 and 100 degree Celsius

Q = mcθ, specific heat capacity = 4.2 kJ/kgK

Q = 2*4.2* (100 - 0) = 840 kJ

For conversion to steam at 100 degrees Celsius

Q = mL , L = latent heat of vaporization = 2256 kj/kg

Q = 2 * 2256 = 4512 kJ

Total heat = 672 + 840 + 4512 = 6024 kJ

= 6 024 000 J

But 1 calorie = 4.2 J

Therefore 6 024 000 J will be: 6 024 000/4.2 ≈ 1 434 286 Calories

≈ 1 434 kCalories

If this standing wave is 48.8 meters long from end to end, what is the wavelength?

Mrrafil [7]

The wavelength of a standing wave is 8.13 m.

<h3>What is a wavelength?</h3>

The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.

The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.

The given data in the problem is;

String length(L)= 48.8 metere

Wavelength(λ)=?

The length of the wave having n nodes is found as;

L=nλ

Substitute the given value;

48.8 = 6λ

λ= 8.13 m

Hence, the wavelength of a standing wave is 8.13 m.

To learn more about the wavelength, refer to the link;

Suppose a skydiver (mass = 75 kg) is falling toward the Earth. When the skydiver is 100 m above the Earth he is moving at 60 m/s

Andrej [43]

Answer:

Potential energy = 73.575 kJ

Kinetic energy = 135kJ

Total mechanical energy = 208.575 kJ

Explanation:

The potential energy of a body is given by the expression, PE = mgh, where m is the mass of the body, g is the acceleration due to gravity value and h is the height of the body.

The kinetic energy of a body is given by $KE=\frac{1}{2} mv^2$ , where v is the velocity and m is the mass of body.

Total mechanical energy = Kinetic energy + Potential energy

$KE=\frac{1}{2} mv^2=\frac{1}{2} *75*60^2= 135000J = 135kJ$

PE = mgh = 75*9.81*100 = 73575 J = 73.575 kJ

Total mechanical energy = Kinetic energy + Potential energy = 135+73.575

= 208.575 kJ

Which sentence states Newton's second law?

Shalnov [3]

Answer:

Force is equal to the change in momentum per change in time.

Explanation:

That situation is described by Newton's Second Law of Motion. According to NASA, this law states, "Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration." This is written in mathematical form as Force = mass.
