To solve this question, we use the wave equation which is:
C=f*λ
where:
C is the speed;
f is the frequency;
λ is the wavelength
So in this case, plugging in our values in the problem. This will give us:
C = 261.6Hz × 1.31m
= 342.696 m/s is the answer.
The four basic units we use in the topic involving electricity are:
1. Volt (V) - used to express voltages
2. Ampere (A) - used for the electrical current
3. Ohm (Ω) - for electrical resistance
4. Watt (W) - for electric power
Answer:
Explanation:
Given data :
Length of rubber tube = 13.6m
Mass of rubber tube = 0.750 kg
mass of object = 740 kg
gravitational acceleration = g = 9.8 m/s²
Solution:
First we will find mass per unit length of the rubber tube μ.
μ = 13.6/0.750
= 18.133 kg/m
tension in tube T = mg = 740×9.8
= 7252 N
now we have the values of T and μ we can find the speed v.
v = √T/μ
v = 19.998 m/s
= 13.6/19.998
t = 0.68 s
The answer would a battery or or an emf device but the best option is going to be A.
if 3kg moves at 4.50 so 50 is 225
