Answer:C
Explanation:
Mass energy of hydrogen fusing into helium
Assumption both thunder and misty are pulling in same direction,
Net force= 1000N+800N-75N=1725N
Mass of wagon = 1725N/1.3ms^-2 = 1327kg
Answer:
The capacitance and the inductance can choose for a car-alarm circuit are
C = 215.27 μF
L = 9.078 μH
Explanation:
,
, 
To determine the capacitance can use the equation

Solve to C'


To find the inductance can use the frequency of the circuit

Solve to L'


Since the tower base is square with a side length of 125 m,
Therefore,

Square root of 31250 = 176.776953 (Diameter)
, so this is the diameter of the cylinder to enclose it, and radius, r = 88.38834765 m and height, h = 324 m.
The volume of cylinder,

Thus, the mass of the air in the cylinder,

Hence, the mass of the air in the cylinder is this more than the mass of the tower.
