Answer:
3. 5.0N/kg
Explanation:
Gravitational field strength = gravitational force/mass of astronaut = 350N/70kg = 5.0N/kg
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.
Answer:
The water level in the bath tub is rising at a rate of 0.0111 ft/s
Explanation:
Volume of the bath tub = (Area of base) × (height)
Area of base = 18 ft² (constant)
Height = h (variable)
V = 18h
(dV/dt) = 18 (dh/dt)
If (dV/dt) = 0.2 ft³/s
0.2 = 18 (dh/dt)
(dh/dt) = (0.2/18)
(dh/dt) = 0.0111 ft/s
Hope this Helps!!!
Answer:
Inductance, L = 0.0212 Henries
Explanation:
It is given that,
Number of turns, N = 17
Current through the coil, I = 4 A
The total flux enclosed by the one turn of the coil, 
The relation between the self inductance and the magnetic flux is given by :
L = 0.0212 Henries
So, the inductance of the coil is 0.0212 Henries. Hence, this is the required solution.
Answer:
The electric bill for June is Rs198000
Explanation:
Convert volt to watt, but in order to do so I need to know the amps and since it is not provided I converted if the amps was 1.
I multiple 50 with 10 then with 30 so I know how much watt the fan takes at June.
Since there are 2 light bulb I multiple 10 with 2 than with 8 than with 30.
15000 watts for the fan,
4800 watts for light bulb,
add them and then times it by 10.
Rs198000
