The equation of motion of a particle is given by,
s =
Let velocity of particle is denoted by v.
The velocity of the particle is given by,
velocity (v) =
v =
v =
v =
Thus, Velocity of particle is given by,
v =
Let acceleration of the particle is denoted by a.
The acceleration of particle is given by,
Acceleration =
a =
a =
a = 12t - 16
Thus, acceleration of the particle is given by,
a = 12t - 16
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.
Answer: A
Can the wave travel through a vacuum
Explanation:
Electromagnetic waves can propagate through space, and vacuum carrying electromagnetic radiant energy without the help of any medium for its propagation. But mechanical wave can't propagate through a vacuum without the help of a medium.
Answer:
The magnitude of the torque due to gravity if it is supported at the 28-cm mark is 0.5 N-m.
Explanation:
Given that,
Mass of the meter stick, m = 0.3 kg
Center of mass is located at its 45 cm mark.
We need to find the magnitude of the torque due to gravity if it is supported at the 28-cm mark. Torque acting on the object is given by :
or
So, the magnitude of the torque due to gravity if it is supported at the 28-cm mark is 0.5 N-m.
B. Kelvins and D. degrees Celsius are the correct answers.
Joules is used to measure energy, while Newtons is used to measure force.
Hope this helps~
