The moon orbiting the Earth
Explanation:
The motion of the moon orbiting the earth is a circular motion. Circular motion is simply the motion of an object in circle at constant speed.
- A cannonball flying from a cannon is a projectile motion and not a circular motion.
- A car moving along a straight track is a linear/translational motion.
- Pendulum of a grandfather clock is a simple harmonic motion.

Answer:
354200J
Explanation:
Given parameters:
Mass of copper bushing = 8kg
Initial temperature = 25°C
Final temperature = 140°C
Unknown:
Quantity of heat required to heat this mass = ?
Solution:
The amount of heat required to heat mass from one temperature to another is given by;
H = m c Δt
where m is the mass
c is the specific heat
Δt is the change in temperature
C is a constant and for copper, its value is 385J/kg°C
Input the parameters;
H = 8 x 385 x (140 - 25) = 354200J
The value of spring constant and the oscillator's damping constant is
K= 6605.667008, b= 0.002884387
Explanation:
For Weakly damping spring oscillator
K/m = W_0^2 (at resonance)
K= mW_0^2
=0.206 * ( 2π * 28.5) ^2
=0.206 * (2π)^2 * (28.5)^2
K= 6605.667008
F = - bV
b= -F/V = -F/ -W_0 * m
=F/W_0 * m
= 0.438N / 2π * 28.5 * 0.848
b= 0.002884387
Answer:
D. hypothalamus
Explanation:
The autonomic nervous system (ANS) is a component of the peripheral nervous system that is in charge of the involuntary functions, this means it regulates the flight-or-fight response, heart and respiratory rate, sexual arousal, urination, etc.<em> The hypothalamus is the integrator of these functions, it receives the information from the nervous system and responds to it.</em>
