Answer:
Weight of the object will be 98 N
Explanation:
We have given mass of the object m = 10 kg
Acceleration due to gravity 
We have to find the weight of the object
Weight of the object is dependent on mass and acceleration due to gravity, it is the product of mass and acceleration due to gravity
So weight of the object W = mass × acceleration due to gravity
So 
So weight of the object will be 98 N
What is the question? if you are looking for the initial velocity of the projectile, then V escape of Earth = 11.2 km / s. divided by three
Vi = 3.73 km/s
Answer:
d.
Explanation:
all because the projector is a lens and the magnifying also the microscope
1. 2500/60 joules/sec
2. 2,500Nm
Answer:
Explanation:
change in flux = no of turns x area of loop x change in magnetic field
= 1 x π 65² x 10⁻⁶ x ( 650 - 350 ) x 10⁻³
= 3.9 x 10⁻³ weber .
rate of change of flux = change of flux / time
= 3.9 x 10⁻³ / .10
= 39 x 10⁻³ V
= 39 mV .
Since the magnetic flux is directed outside page and it is increasing , induced current will be clockwise so that magnetic field is produced in opposite direction to reduce it , as per Lenz's law.
