Answer:
It has a mass of 40 kg.
Explanation:
Because Force = mass x Acceleration or F = m a, we could say that the mass is force/acceleration which in your case is 2,400/60 which equals 40 kg.
Answer:
increases by a factor of 4.
Explanation:
The power dissipated through a resistor is I2RI2R
Current=IResistance=RPower=(current)2×(resistance)=I2RIf we double the current, P=(2I)2R=4I2RCurrent=IResistance=RPower=(current)2×(resistance)=I2RIf we double the current, P=(2I)2R=4I2R
Thus, doubling the current increases the power dissipated through a resistor by a factor of four.
Answer:
1 in is represented as 21.6667 miles
Explanation:
Data provided in the question:
Distance between the city A and the city B = 65 miles
Distance measured by the scale on the map between the city A and the city B = 3 inches
Thus,
3 inches is represented as 65 miles
Thus, applying the unitary method
1 in is represented as 65/3 miles
or
1 in is represented as 21.6667 miles
