Through what angle does it turn during that time interval if the angular acceleration is constant: 32.0rad.
<h3>What is
angular acceleration?</h3>
- Angular acceleration is the term used to describe the temporal pace at which angular velocity varies. Radians per second is the accepted unit of measurement. Consequently, = d d t. Angular acceleration is also known as rotational acceleration.
- Angular acceleration can be calculated by dividing the angular velocity by the acceleration duration. (t). Use pi instead, or the drive speed (n) divided by the acceleration time (t) multiplied by 30. The usual SI unit for the rotational acceleration that results from this equation is radians per second squared (Rad/sec2).
Through what angle does it turn during that time interval if the angular acceleration is constant:
v(initial) = 4rad/s
v(final) = 12
t = 4 sec
a = ?
v(final) = v(initial) + at
12 = 4 + a(4)
a = 2 rad/sec2
s = ?
v(initial) = 4rad/s
v(final) = 12
a = 2rad/sec2
144 = 16 + 4s
s = 32 rads
d) 32.0rad.

Answer:
311,850 N
Explanation:
We can solve the problem by using Newton's second law:
where
F is the net force exerted on the object
m is the mass of the object
a is the acceleration
In this problem, we have
m = 27 kg is the mass
a = 11,550 m/s^2 is the acceleration
Solving for F, we find:
Answer:
A. 19.8 cm.
Explanation:
The apparent depth of the combination is
As it mentioned that the two clear but non-mixing liquid having depth of 15 cm that placed in a glass container together
Also the refractive indices would be 1.75 and 1.33
Based on the above information
As we know that
Refractive indices = real depth ÷ apparent depth
1.33 ÷ 1.75 = 15 ÷ apparent depth
So, it would be 19.736842 cm
Now the combination of apparent depth would be
= ( 19.736842 + 15) ÷ (1.75)
= 19.8 cm
hence, the correct option is A.
Answer: A difference in properties between two interacting systems as explained below.
Explanation: Planetary differentiation is the process of separation of different parts of a planetary body as a result of their physical or chemical behavior.
Causes for Physical Differentiation:
1. Melting and crystallization of source rock.
2. Differences in densities
3. Thermal diffusion
4. Collision of large bodies
Chemical Differentiation accounts for differences in chemical compositions of different materials.
The differentiation, or organization, of the Earth into layers led to the formation of a core, a crust, and eventually continents. The light elements were driven from the interior to form an ocean and atmosphere.
We only need to look at Newton's 2nd law of motion:
Net force = (mass) x (acceleration)
If the net force on an object is zero, then either its mass or its acceleration must be zero. If it's called an "object", then its mass isn't zero, so its acceleration is zero.
