Answer:
the answer is b
Explanation:
because you multiply speed times wavelength
Answer: D.) 3hrs
Explanation:
Given the following :
A boat can move at a constant velocity of 8 km/h; How long will it take for the boat to move 24 km
Recall:
Velocity = Displacement / time
For the boat to travel a distance of 24 km at a constant velocity of 8km /hr
Time taken = Displacement(distance moved) / velocity
Time taken = 24km / 8kmhr^-1
Tine taken = 3hrs
Answer:
momentum=mass×velocity
momentum =400kg×20m/s=8000kg.m/s
Answer:
The answer to the question is
The magnitude of the displacement needed to get the ball into the hole in just one putt is 1.746m in the direction of 23.41° north east
Explanation:
With trigonometric relation and the attached diagram we have
From the diagram the location of the hole is 3.32m- (1.57 cos45 +0.78co45)m North and
1.57sin 45 – 0.78 sin 45 meters west
1.658m north and
0.55m east
Thus the direction of the hole is 26.41 degrees
North east
The magbitude of the displacement is displacement is gotten from the relation diplacement of x and y =√(x²+y²)
∠26.41°
120m speed of a wave if the wavelength
