Answer:
LONGITUDINAL WAVE
Explanation:
As we know that there are two type of propagation of wave
1) Transverse wave :
in transverse nature of waves the energy is propagated into the medium in perpendicular to the wave propagation.
So here in transverse waves the medium molecules will start oscillating in perpendicular direction
2) Longitudinal wave
Here in this type of wave the medium molecules will start oscillating in the direction of propagation of waves. So here the medium molecules will oscillate in the direction parallel to the wave propagation
so correct answer is
Longitudinal waves
Answer:
B. Spring
Explanation:
The waters of a lake will be the most layered in the spring because of the melting of the ice (which is just frozen water) and the direct heat going into the lake causing the warm water to rise up and the colder water to move further down, which creates even more layers.
Answer:
78 N s
Explanation:
The impulse exerted on the ball is given by:
where
F is the magnitude of the force
is the duration of the collision
In this problem,
F = 39 N
Substituting,
Answer:
(a) 18.87 V
(b) 23.81 V
(c) 20.75%
Explanation:
The answers are given in the pictures. I have attached the pictures because circuits were needed to be drawn which are easier to understand when done on page. The page are numbered on top left corner.
To solve this problem we will use the concepts related to thermal expansion in a body for which the initial length, the coefficient of thermal expansion and the temperature change are related:
Where,
= Change in Length
= Coefficient of linear expansion
= Change in temperature
= Initial Length
Our values are:
Replacing we have,
Therefore the change in milimiters was 0.4126mm
