Answer:
118.8 N
Explanation:
Weight of the light, W = 214.8 N
Angle between two wires, 2θ = 129.4°
Let t be the tension in each wire. Now the vertical components of tension is balanced by the weight of the light.
2 T Sinθ = W
2 x T x Sin 64.7° = 214.8
1.808 T = 214.8
T = 118.8 N
Thus, the tension in each wire is 118.8 N.
Answer:
116 N

Missing question: (found on google)
<em>"What is the force of the pitcher's hand on the 0.145 kg ball during this acceleration phase?
</em>
<em>Express your answer with the appropriate units."</em>
Solution:
First of all, we need to calculate the acceleration of the ball, given by
where
v = 40 m/s is the final velocity
u = 0 is the initial velocity
is the duration of the acceleration phase
Substituting,
Now we can find the force exerted on the ball by using Newton's second law:
where
m = 0.145 kg is the mass of the ball
a is the acceleration
Substituting,
Answer:
When the head moves, fluid within the labyrinth moves and stimulates nerve endings that send impulses along the balance nerve to the brain. Those impulses are sent to the brain in equal amounts from both the right and left inner ear.
Explanation:
16/9 m/s^2
negative 4/3 m/s^2
14 m/s
the last one is too detailed to do in my head while on the bus; sorry
