Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
There should be an image that should accompanied your question, I was able to chcek it from other sources. the acceleration of the block when the scale reads 32N is <span>4.0 m/s*s</span>
Sublimation is the state shown in the model
Answer:
the transfer of heat through convection
Explanation:
i just know
Answer:
The acceleration of the ball is constant and equal to -9.81 m/s² (acting downwards)
The velocity of the ball reduces at a constant rate with time on its way up
Explanation:
The motion of the ball upwards is described by the following equation;
v = u - g × t
v² = u² - 2 × g × s
Where;
v = The final velocity of the ball
u = The initial velocity of the ball
g = The acceleration due to gravity = Constant
s = The height of the bass after a given time, t
t = The time in which the ball is rising
Therefore, the acceleration of the ball = The acceleration due to gravity (Constant) = -9.81 m/s²↓
From v = u - g × t = u - 9.81 × t , the velocity of the ball reduces at a constant rate with time on its way up.
Answer:
c. The group speed is less than the phase speed.
Explanation:
For an individual the speed is given by v phase = w/k
w is angular frequency and k is wave number.
This is called phase speed. Group speed is the speed of wave packet.The rate of advance of a crest on a single wave point which is fixed phase.
