What happens when solar energy heats a body of water?

2 answers:

6 0

Explanation: Evaporation happens when a liquid substance becomes a gas. When water is heated, it evaporates. The molecules move and vibrate so quickly that they escape into the atmosphere as molecules of water vapor (Dunn,1993).

The correct answer would be Evaporation. When the heat heats water too a a boiling point then it turns into steam also know as Evaporation

loris [4]

Answer:

She would travel 175.5 m in the same amount of time

Explanation:

Here is the complete question:

Seven bicyclist are racing. Each bicyclist rides for 9s. If a bicyclist, with initial velocity of zero, steadily gained speed until reaching a final velocity of 39m/s, how far would she travel during the race in the same amount of time)?

Explanation:

To determine how far she would travel in the same amount of time, that is the distance she would cover in the same amount of time

From the question,

The bicyclist has an initial velocity of zero

That is, u = 0 m/s

and a final velocity of 39 m/s

That is, v = 39 m/s

Each bicyclist rides for 9s,

She also traveled for the same amount of time

that is, t = 9s

To determine the distance,

From one of the equations of motion for linear motion

s = $\frac{1}{2}$ t(u + v)

Then

s = $\frac{1}{2}$ (9)(0+39)

s = 4.5 (39)

s = 175.5 m

Hence, she would travel 175.5 m in the same amount of time

A new moon is discovered orbiting Neptune with an orbital speed of 9.3 103 m/s. Neptune's mass is 1.0 1026 kg. What is the

grandymaker [24]

Answer:

The radius of the moon's orbit, R = 7.715 x 10⁷ m

The orbital period of the moon, T = 14.48 hr

Explanation:

Given,

The orbital speed of the moon, v = 9.3 x 10³ m/s

The mass of Neptune, M = 1.0 x 10²⁶ Kg

The orbital velocity of the moon is given by the relation

$v = \sqrt{\frac{GM}{r+h}}$ m/s

Where,

r + h = R → radius of the moon's orbit

Therefore squaring the above equation and solving for r +h. The equation becomes

r + h = GM / v²

Substituting the given values in the above equation

R = (6.673 x 10⁻¹¹ x 1.0 x 10²⁶) / (9.3 x 10³)²

= 7.715 x 10⁷ m

The radius of the moon's orbit, R = 7.715 x 10⁷ m

The orbital period of the moon is given by the relation

T = 2π/ω

= 2πR/v ∵ ω = v/r

Substituting the values in the above equation

T = (2 x π x 7.715 x 10⁷ )/ 9.3 x 10³

= 52125.72969 s

= 14.48 hr

The orbital period of the moon, T = 14.48 hr

If you slosh the water back and forth in a bathtub at the correct frequency, the water rises first at one end and then at the ot

notka56 [123]

Answer:

Velocity(v) = frequency(f) × wavelength

f = 0.3165

Wavelength = 2×length(L)

L = 157cm

Convert the length in centimetres to metre = 1.57m

v = 2×1.57 × 0.3165

v = 0.99m/s

Approx. 1m/s

Explanation:

The velocity of a wave is the product of its frequency and it's wavelength. The frequency is already known. The wavelength is the distance between two successive wave crests which is formed by sloshing water back and forth in the bath tub. Sloshing water to one end of the tub will produce a wave crest first at that end then the other completing a cycle. The wavelength will be twice the length of the bath tub as it is the distance that both crests are formed.

Wave crest is the highest point of a wave, and in this case is where the water rises to a high point in the bath tub

what is the acceleration of a cabinet of mass 45 kilograms if jake and ted push it by applying horizontal force of 25 newtons an

Reptile [31]

Forces in a single plane can simply be added together to find the resultant force. They are both in the same direction so the signs are the same. Hence resultant force = 25 + 18 = 43N.

By Newton's 2nd Law of Motion (which, for constant mass, produces the relation F = ma), a = F/m = 43/45 = 0.95ms^-2 (2sf)
