Which cools faster, land or water? Give a suitable reason for your answer.

Physics
1 answer:
9966 [12]2 years ago
7 0

Answer: Land cools faster than water

Reason: Water has high specific heat capacity, so it absorbs huge amount of heat energy to increase comparatively small amount of temperature. Loosing a large amount of heat requires more time, so <em>water takes more time to cool down. </em>

Do tides depend more on the strength of gravitational pull or on the difference in strengths? explain.
SSSSS [86.1K]
Tides are influenced by the force of gravity exerted by the earth, moon and the sun. The sun has a larger mass than the moon and as such has a greater gravitational pull on the earth. the moon however has greater influence over the tides because they are caused by the difference in gravity fields. This means that the moon is the dominant influence due to the fact that the fractional difference in its force across the earth is greater than that seen from the sun.

In a milkans apparatus,an oil drop of weight 2.0×10^-15kg accquires two surplus electrons. when a Potential difference of 620 vo
andriy [413]

Answer:

r = 9.92 mm

Explanation:

Given that,

Mass of oil drop, m=2\times 10^{-15}\ kg

It acquires 2 surplus electrons, q = +2e =3.2\times 10^{-19}\ C

Potential difference, V = 620 V

Thie potential difference is applied between the pair of horizontal metal plates the drop is in equilibrium.

We need to find the distance between the plates.

At equilibrium,

mg = qE

Since, E = V/r (r is distance between plates)

mg=\dfrac{qV}{r}\\\\r=\dfrac{qV}{mg}\\\\r=\dfrac{3.2\times 10^{-19}\times 620}{2\times 10^{-15}\times 10}\\\\=0.00992\ m\\\\=9.92\ mm

So, the distance between the plates is 9.92 mm.

How much would a 70.0-kg person weigh on Mercury?
Natalija [7]

As weight =w =mg

g= gravitational acceleration on mercury = 3.7m/sec2

Mass of person =m= 70 kg

So w =(70kg)(3.7m/sec2)

w= 259 kgm/sec2

W= 259 N
