Explanation:
The vertical component the velocity of the projectile is 15 m/s x sin 30 = 7.5 m/s.
The body is accelarating downwards at 10 m/s^2.
This means that every second its upward velocity reduces by 10 m/s.
So if the body is travelling upwards at 7.5 m/s then how long does it take for the velocity to become 0?
(7.5 m/s) / (10 m/s^2) = 0.75 s
Answer:
The angular acceleration of the centrifuge is -231.74 rad/s².
Explanation:
Given that,
Angular speed = 3500 rev/min = 366 rad/s
We need to calculate the angular displacement
Using formula of angular displacement
Put the value into the formula
We need to calculate the angular acceleration
Using equation of motion
Hence, The angular acceleration of the centrifuge is -231.74 rad/s².
<span>Brownian
motion is the random movement of colloidal particles suspended in a fluid. It is
caused by random collisions of the molecules in the fluid medium. The particles
in the solution or colloids are in constant random movement. A colloid has
properties boundary to a homogenous and heterogeneous mixture. However in
Brownian movement, the larger the size of a particle, the lesser its motion and
the smaller the size of the particle, the higher is motion. Colloids in general
have larger particle size and therefore it Brownian motion is sluggish. The statement
is false.</span>
Mujhe nhi pata sorry. Lekin mai bhut logo ko jaanti hoon jo iss savaal ka jawaab de sakte hai.
