Answer:
Private jet is 200 mph
Commercial jet is 225 mph
Explanation:
Let the speed of private jet be x mph therefore the speed of commercial jet will be 2x-175 mph
The distance is the same
Speed is distance per unit time hence distance is product of speed and time
Distance by private jet is 9x
Distance by commercial jet is 8(2x-175)
Since the distance is the same
9x=8(2x-175)
9x=16x-1400
7x=1400
X=200
Then 2x-175= 400-175=225
Speed of private jet is 200 mph while commercial jet is 225 mph
Explanation:
Momentum = mass × velocity
p = (65 kg) (5 m/s)
p = 325 kg m/s
Answer:
The distance moved by the boat is 0.70 m.
Explanation:
Given that,
Mass of Romeo = 77.0 kg
Mass of Juliet = 55.0 kg
Distance = 2.70 m
Mass of boat = 80.0 kg
Let the distance moved by the boat is x.
as the center of mass will not change it's position
We need to calculate the distance moved by the boat
Using formula for distance
Put the value into the formula
Hence, The distance moved by the boat is 0.70 m.
Answer:
Magnetic field = 1.41 T
Explanation:
Magnetic field of solenoid, B = μnI
μ = 4π x 10⁻⁷N/A²
Number of turns per meter,
Current, i = 18.2 A
B = μnI = 4π x 10⁻⁷ x 6.15 x 10⁴ x 18.2 = 1.41 T
Magnetic field = 1.41 T
