Answer: The correct answer is a.
Explanation:
Electromagnetic wave is a wave in which the magnetic field and the electric field are perpendicular to each other.
Both fields are directed in the direction of the propagation of the electromagnetic wave. It travels with the speed of the light.
The motion of the electric field produces both electric field and the magnetic field.
The electromagnetic waves are produced when an electric charge vibrates or accelerates.
Therefore, the correct option is (a).
Large global wind systems are created by the uneven heating of the Earth's surface. Warm air rises at the equator and moves toward the poles. At the poles, the cooler air sinks and moves back toward the equator.
Answer:250.03m
Explanation:
Initial velocity =u=51mph
Angle=β=37
Acceleration due to gravity=g=10
The distance covered by the football is the range
Range=(u^2xsin2β)/g
Range=(51^2xsin(2x37))/10
Range=(51x51xsin74)/10
Range=(2601xsin74)/10
Range=(2601x0.9613)/10
Range=(2500.3)/10
Range=250.03m
The answer is , Conductance
Answer:
2.177088 * 10^-8 N
Explanation:
solution;
mass(m1) = 1 * 10 kg
mass(m2) = 8 * 102 kg
distance(d) = 5m
universal gravitational constant (G) =6.67 * 10^-11
we know that,
gravitational force = (G*m1*m2)/d^2
=((6.67 *10^-11) *(1 *10)*(8 *102))/5^2
=(5.44272 * 10^-7)/25
=2.177088 *10^-8
Gravitational force = 2.177088 * 10^-8
