Explanation:
Average speed =total distance ÷ total time
speed = d ÷ t
d= 74400
t= 16
then,
speed = 74400÷16
=4650
A graph. This can be called a graph. A graph is the answer.
Answer:
Explanation:
The full definition of a computer is
A computer is a machine(electronic device) that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse.
It is not necessary that a computer have network capacity, as far as it can process data into information, accept input and store results.
The correct option is A
Answer:
0.225 KJ kinetic energy is used for a person of mass 50 Kg running at speed of 3 m/s.
Explanation:
Given:
mass = 50 kg
velocity = v = 3 m/s
To Find :
Kinetic energy = ?
Solution:
Kinetic energy of an object is the energy that it possesses due to its motion.
The formula for kinetic energy is given as
But we required kinetic energy in KiloJoules i.e KJ
1 K = 1000 =
