Explanation:
the unknown resistance is 9ohm
Answer: The wave is traveling in the - x direction.
Explanation: The parameter in a wave function determines the direction of the wave is "ωt"
Where ω = angular frequency(in hertz ) and t = time taken (in seconds)
The product of ωt = 2π which is angular displacement in radian.
A negative value of the of ωt means the wave is traveling in the negative direction.
Also a positive value of sin ωt means the wave is traveling in the positive direction
Answer:
112J (3 s.f.)
Explanation:
KE= 1/2mv^2
where KE is kinetic energy, m is the mass in kg, and v is the velocity (or speed to take it simply) in m/s.
KE= 1/2(6)(6.1^2)
KE= 111.63
KE= 112J (3s.f.)
Answer:
The the speed of the car is 26.91 m/s.
Explanation:
Given that,
distance d = 88 m
Kinetic friction = 0.42
We need to calculate the the speed of the car
Using the work-energy principle
work done = change in kinetic energy
Put the value into the formula
Hence, The the speed of the car is 26.91 m/s.
