Hi!
The energy of the block is 4 m/s
To calculate this, you need to use the equation for
kinetic energy. The block is sliding (i.e. it's moving). If the object is sliding across a level surface, the only energy it has is kinetic energy, because
there is no change in potential energy (which changes with height). So, the mechanical energy will be pure kinetic energy. The equation is the following, derived from the expression for kinetic energy:

Explanation:
Given that,
Current, I = 0.015 A
Voltage, V = 240 volts
We need to find the resistance. Using Ohm's law we can find it as follows :

So, When a current of 0.015 A passes through human body at 240 volts p.d it causes 16000 ohms of resistance.
The answer would be B..
Since sand can heat up quickly, it will also cool off quickly. But water takes a long time to heat up and cool down.
Answer:
Explained
Explanation:
Compared to Jupiter, Saturn's atmosphere is more calm with fewer disturbances or storms.
The Atmosphere in Jupiter is highly violent and thinner as compared with Saturn.
The layers of atmosphere on Saturn is thicker because of lower gravity of Saturn and hence they are calmer.
