Answer:
120 miles
Explanation:
Speed = distance traveled/ time taken.
Distance traveled = speed * time taken
Speed = 40 miles per hour, time = 3 hours.
Distance = 40*3
The train's traveled distance is 120 miles.
Answer:
-1.7534 Kg.m/s
Explanation:
Momentum, p is a product of mass and velocity, expressed as p= mv where m is the mass and v is the velocity which is dependent on the direction. Taking left as negative and right as positive then the initial momentum will be
p=-2.42*3.92+(3.7*2.09)=-1.7534 Kg.m/s
Answer:
velocity of the car is 7.3516 m/s
Explanation:
M1v1a + m2v1b = m1v2a + m2v2b
775*30 + 1475*0 = 775*v2a+1475*11.9
Let v2a be x
23250 + 0 = 775x + 17552.5
775x = 23250-17552.5
775x = 5697.5
X = 7.3516 m/s
Answer:
Neap tides, which also occur twice a month, happen when the sun and moon are at right angles to each other. ... This occurs twice each month. The moon appears new (dark) when it is directly between the Earth and the sun. The moon appears full when the Earth is between the moon and the sun.
