The one that help create radio waves is :
Changing electric and magnetic fields applied at right angles
Radio waves are transverse wave, which means that the oscillations occurring perpendicular to the direction of energy transfer
hope this helps
Diceplacement is the distance an object has traveled in a certain direction
for example, if you were to walk North for 20m, then east for 40m, the <u>distance</u> you have traveled is 60m however your displacement is the distance between your starting position and your end position;
sqrt(20^2+40^2) = 44.7m
and because displacement is a vector, there needs to be a direction;
sin(theta)=40/44.7
theta=63.4 degrees East of North
therefore the true displacement is 44.7m at 63.4 degrees East of North
Newton's Third Law States that Every Action Has an Equal and Opposite Reaction. To stop or slow down an object, a force must be applied in the direction opposite to that of the object's motion. Exerting a force results in an equal force in the opposite direction (like the recoil a person feels when firing a gun)
Answer : The energy consumed by bulb in 24 hours is, 8.64 × 10⁶ J
Explanation :
As we are given that:
1 watt = 1 J/s
So,
100 watt = 100 J/s
Now we have to calculate the energy consumed by bulb in 24 hours.
As we know that:
1 hr = 60 min
1 min= 60 sec
So,
24 hr = 24 × 60 × 60 sec = 86400 sec
As, the energy consumed by bulb in 1 second = 100 J
So, the energy consumed by bulb in 86400 second = 86400 × 100 J
= 8.64 × 10⁶ J
Thus, the energy consumed by bulb in 24 hours is, 8.64 × 10⁶ J
Answer:
By increasing the temp the faster the heat is transferred so faster the substance cools
And vice versa
