Answer:
An acute injury is sudden and severe such as a broken bone. A chronic injury develops and worsens over an extended period of time like shin splints
Explanation:
Answer:
The ratio of lengths of the two mathematical pendulums is 9:4.
Explanation:
It is given that,
The ratio of periods of two pendulums is 1.5
Let the lengths be L₁ and L₂.
The time period of a simple pendulum is given by :
or
Where
l is length of the pendulum
or
....(1)
ATQ,
Put in equation (1)
So, the ratio of lengths of the two mathematical pendulums is 9:4.
Answer:
Temperature of the object
Explanation:
According to kinetic theorem of gases, the temperature of a gas is a measure of the of the average kinetic energy of the gas particle.
A particle can either exist as solid, liquid or gas.
For solid, the particles are fixed as they rotates and vibrate about a mean position.
The particle of an object is a solid particle.
In accordance to kinetic theorem, the temperature of an object related to the average kinetic energy of the particles in the object.\
Temperature: This can be defined as the degree of hotness or coldness of an object.
Radio waves have the longest wavelengths
Answer:
5 m/s
Explanation:
Here we can see there is no external force acted on a two masses when we consider the motion. If there is no external forces then momentum is conserved.
Initial momentum = Final momentum
0.5 × 10 = 1 × V
V = 5 m/s
