Answer:
3.18 V
Explanation:
RMS voltage of a generator is given by:
Given:
Output voltage at t =0.01 s is 4.2 V
Answer:
500 N
Explanation:
Natural bouyency will keep the diver in the same place, no matter what the mass of gfs. This means if the diver is displacing with a weight of 500 N, the upthrust will also be 500 N.
Answer:
18 days
Explanation:
A person normally consumes 2200 Cal per day
An adult burns 2000 Cal per day normally
Energy converted to fat 2200-2000 = 200 Cal
Number of days will be given by
The number of days would be 18 days
The correct answer is A: controlled for useful work
Answer: 637N
Explanation:
Force needed to lift box = ?
Mass of box = 65kg
Acceleration due to gravity, g = 9.8m/s2
Recall that Force applied depends on the mass of an object moved against gravity.
Thus, Force = Mass x acceleration due to gravity
F = mg
F = 65kg x 9.8m/s2
F = 637N
Thus, 637 newton of force is needed to lift a 65kg box
