His weight depends on where he is, because
Weight = (mass) x (gravity in the place where the mass is) .
For example:
-- If this man is on Mars, his weight is (110 kg) x (3.7 m/s²) = 408 Newtons
-- If he is on the Moon, his weight is (110 kg) x (1.6 m/s²) = 176 Newtons
-- If he is on Earth, his weight is (110 kg) x (9.8 m/s²) = 1,078 Newtons
-- If he is in a spacecraft coasting from one to another, his weight is zero.
Answer:
power = 23.2 mW
Explanation:
given data
resister r = 5.80 kΩ
current measures I1 = 3.10 m A
measure current I2 = 1.10mA
solution
we get here I total
I = current 1 - current 2
I = 3.10 - 1.10
I = 2 mA
so here power will be
power = I²×R .............1
power = 2² × 5.80
power = 23.2 mW
Answer:
2.866 x 10^8 J
Explanation:
Thermal conductivity, K = 0.040 W/m^2 k
Area of the wall, A = 470 m^2
Thickness, d = 17 cm = 0.17 m
difference in temperature, ΔT = 30° C
The rate of heat flow is H.
Time, t = 1 day = 1 x 24 x 60 x 60 second = 86400 second
By use of formula of heat flow
H = 2.866 x 10^8 J
