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:
The gravitational acceleration is 5.03 m/s² on the surface of the planet.
Explanation:
Frequency:
The number of complete oscillation per unit second is called frequency.
Angular frequency:
Angular frequency is the product of the oscillation frequency and the angle thought which the object moves.
Angular velocity
Given that,
Number of oscillation= 247, time= 793 s, length of the pendulum=1.31 m
Hz.
Angular velocity
=1.96 rad/s
We know that,
g= gravitational force of the planet
= length of the pendulum
= angular velocity
m/s²
= 5.03 m/s²
The gravitational acceleration on the surface of the planet is 5.03 m/s².
Answer:
By the why,metals have important characteristics.Conductivity By saying that metals are good conductor of heat/electricity we mean that metal allow heat/electricity to pass through them easily. ....Ductility The property which allows the metals to be drawn into thin wires is called ductility.
