Answer:
1.41 m/s, 7.85 rad/s
Explanation:
We can start by calculating the tangential velocity, which is given by:
where
r = 18 cm = 0.18 m is the radius of the circumference
T = 0.8 s is the period
Substituting,
Now we can also calculate the angular velocity, which is given by:
where again,
T = 0.8 s is the period
Substituting,
Radio waves are neither Longitudinal or transverse.
Only mechanical waves are either transverse or longitudinal. Examples are Ocean waves, Earthquake waves, and sound waves.
Radio waves are light waves, which means they do not require a medium to travel through.
Answer: chemical property
Explanation:
Openness to experience, Neuroticism, agreeableness, Extroversion, Conscientiousness
Answer:
(i) 208 cm from the pivot
(ii) Move further from the pivot
Explanation:
(i) Sum of the moments about the pivot of the seesaw is zero.
∑τ = Iα
(50 kg) (10 N/kg) (2.5 m) + (60 kg) (10 N/kg) x = 0
1250 Nm + 600 N x = 0
x = -2.08 m
Kenny should sit 208 cm on the other side of the pivot.
(ii) To increase the torque, Kenny should move away from the pivot.
