a) KE=0.5*mv^2==0.5*145*25^2=45312.5 J
b) PE=mgh=145*9.8*3.5=4973.5 J
c) ME=KE+PE=m(0.5v^2+gh)=62524 J
<span>They would feel that the water is cold.
</span> The atmosphere is heated both by the Sun and by the Earth's surface. Water radiates heat differently than land, so the air temperature over the ocean is usually different than the air temperature over land. <span>
The difference in air temperature over land compared to over water causes convection currents in the atmosphere. How would a person at the beach experience these convection currents?
</span>They would feel that the water is cold.
NOT:
They would feel the heat of the Sun.
They would feel that the sand is hot.
<span>They would feel wind as the air moves.</span>
Since the boot-print was left there nearly 50 years ago, there has been very little wind and very little rain in that area, and plus, there have been very few people or other animals walking around in that spot to disturb it.
FORMULA:
- V = IR, where V = P.D; I = Current; R = Resistance.
ANSWER:
Total equivalent resistance for circuit:
R(eq) = R1 + R2 [It is in series]
Now, Current passing through whole circuit:
I = V/R
We know that, In series combination current passing through whole circuit is same.
So, V¹ = IR¹
V¹ = 1/50 × 330
And V² = IR²
V² = 1/50 × 470
