Explanation:
using the formula: S=ut+½gt², where u=0, S=?, g=8m/s², t=10seconds.
S=ut+½gt² ("ut" term will cancel because u=0).
=> S= ½gt²
=>S = ½×8×10²
=>S = 4×100
=>S = 400m .
Therefore, the distance traveled by the body in 10s is 400m.
hope this helps you.

Explanation:
= thickness of the floor = 0.159 m
= thermal conductivity of wooden floor = 0.141 Wm⁻¹ ⁰C⁻¹
= Temperature of the interior of the cabin = 18.0 ⁰C
= Temperature of the air below the cabin = - 16.4 ⁰C
Difference in temperature is given as
= Difference in temperature = ⁰C
= Area of the floor = 13.4 m²
= Rate of heat conduction
Rate of heat conduction is given as
W

Answer:
The resistance of the bulb is 1000 ohms.
Explanation:
What is the resistance of a bulb that is connected to a 20 v source through which a current of 20 mA passes
We have,
Voltage of the bulb is 20 V and the current passes is 20 mA.
It is required to find the resistance of the bulb. The relation between resistance, current and voltage is given by using Ohm's law as :
V = IR
R is resistance
So, the resistance of the bulb is 1000 ohms.
