Answer:
- it turns electrical signals into radio waves so they can travel sometimes thousands of kilometers around the Earth or even into space and back.
Explanation:
In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as radio waves. I HOPE THIS HELPS:)
Answer:
A marble of 15 mm
Explanation:
so lapilli is the size classification of tephra. it is the material that comes out in air during volcanic eruption. the word lapilli means little stones and its size ranges from 2 mm to 64 mm. so the object which has same size as lapilli is the marble.
#1
for the block of mass 5 kg normal force is given as
friction force is given as
Net force is given as
now we know that
#2
Normal force is given as
now we know that
as object moves with constant velocity
now for coefficient of friction we can use
#3
net force upwards is given as
mass is given as
now as per newton's law we can say
#4
As we know that when block is sliding on rough surface
part a)
net force = applied force - frictional force
part b)
for coefficient of friction we can use
here normal force is given as
now we have
#5
if an object is initially at rest and moves 20 m in 5 s
so we can use kinematics to find out the acceleration
now net force is given as
#6
an object travelling with speed 25 m/s comes to stop in 1.5 s
so here acceleration of object is given as
now the force is gievn as
