Hope this helps you
Answer:
36 W
Explanation:
Power = work / time
Work = force × distance
P = F d / t
P = (72 N) (1.0 m) / (2.0 s)
P = 36 W
Answer:
The tension in the cord is 24.1 Newton
Explanation:
<u>Step 1:</u> Data given
mass of the ball = 1.13 kg
Cord = 0.50m
velocity = 2.4 m/s
<u>Step 2:</u> Calculate the tension
Fnet = F(c)
T - F(g) = F(c)
⇒ with F(g) = force of gravity = m*g
⇒ with F(C) = centripetal force = (mv²)/r
T = (mv²)/r + mg
⇒ with m = mass = 1.133 kg
⇒ with v = velocity = 2.4 m/s
⇒ with r = radius = 0.50 m
T = (1.13 * 2.4²) / 0.50 + 1.13 * 9.81
T = 24.1 Newton
The tension in the cord is 24.1 Newton
Answer:
It is a technique called water displacement method
Mass of an irregular object can be measured using a physical balance
Explanation:
- It consists of a calibrated glass cylinder containing water.
- The initial level of water column is noted
- The irregular object is submerged into it. The water level rises.
- The level of the water column is noted.
- The difference between the final and initial level of the water column gives the volume of the irregular object.
- The method used to find the volume of irregular shaped object is called the water displacement method.
