Answer:
Coal, crude oil, and natural gas are all considered fossil fuels all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago.
Explanation:
Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago. A fossil fuel is a natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.
Answer:
226.2 m/sec
Explanation:
We have given
The plank's constant
Mass of electron
Now according to Heisenberg uncertainty principle
So
Displacement of a body is always in a straight line in the direction of the final position regardless of the path taken to reach the final position.
Therefore, the displacement of the car can be obtained by joining the car's initial position to the final position and then counting the number of squares covered by the line. Then we multiply the number of squares by the scale and note the direction of the final position from the initial.
that is: 4×1km= 4km North since displacement is a vector.
Answer:
Part b)
Part c)
Explanation:
The two components of the velocity of the ball is given as
Part a)
now we know that the displacement in y direction is given as
so we have
Part b)
Distance of the ball in x direction of the motion is given as
Part c)
In x direction the velocity will remain the same always
while in Y direction we can use kinematics
