Answer:
Explanation:
Time = (distance) / (average speed)
Time = (4,700 km) / (790 km/hr) = 5.9494 hours (rounded)
= 5hrs 56min 58 sec (rounded)
(4,700 km) / (1.609344 km/mile) = 2,920 miles
Speed = (distance covered) / (time to cover the distance)
(2,929 miles) / 5.9494 hours) = 491 miles per hour
Answer:
The answer is "Including all three studies of 0s to 2s, that shift in momentum is equal".
Explanation:
Its shift in momentum doesn't really depend on the magnitude of its cars since the forces or time are similar throughout all vehicles.
Let's look at the speed of the car
We use movies and find lips
The moment is defined by
The moment change
Let's replace the speeds in this equation
They see that shift is not directly proportional to the mass of cars since the force and time were the same across all cars.
D. velocity
Velocity depends on speed and direction
Answer:
Peak current= 84.86 A
Area of each turn = 0.029 m^2
Explanation:
The peak value of current can be obtained from Irms= 0.707Io. Where Io is the peak current.
Hence;
Irms= 60.0A
Io= Irms/0.707
Io = 60.0/0.707
Io= 84.86 A
Vrms= 0.707Vo
Vo= Vrms/0.707= 170/0.707 = 240.45 V
From;
V0 = NABω
Where;
Vo= peak voltage
N= number of turns
B= magnetic field
A= area of each coil
ω= angular velocity
But ω= 2πf = 2×π×95= 596.9 rads-1
Substituting values;
A= Vo/NBω
A= 240.45/550×0.025×596.9
A= 0.029 m^2
