Explanation:
The inner part of earth is mainly of two parts
- Mantal
- Core
Mantal and core both consists of Hot magmas .
So volcanism is required
Answer:
Yes
Explanation:
Element D will also burn in oxygen, because elements classified under same group has similar physical or chemical properties.
Given,
Frequency of microwaves = 3 x 10^9 Hz
We know that,
Velocity (c) = Frequency x Wavelength
Velocity of light (c) = 3 x 10^8 m/s
Therefore,
Wavelength = Velocity ÷ Frequency = (3 x 10^8) ÷ (3 x 10^9) = 0.1 m
Answer:
bumper cars colliding- inelastic
man jumping in a cab- perfectly inelastic
mud sticking to car - perfectly inelastic
hat being sat on door being slammed- inelastic
ball bouncing- elastic
Explanation:
In a perfectly inelastic collision, the objects stick together after collision and move with a common velocity. Maximum kinetic energy is lost during such collision.
For an inelastic collision, kinetic energy is partly lost and the colliding objects move apart at different velocities. This is often encountered in real life situations.
For an elastic collision, both momentum and kinetic energy are conserved. The object rebounds with the same relative velocity with which it approached.
