Answer:
a) 12.528 m/s
b) 15.344 m/s
Explanation:
Given:
Mass of the child, m = 34.9 kg
Height of the water slide, h = 16.0 m
Now,
a) By the conservation of energy,
loss in potential energy = gain in kinetic energy
mgh =
where,
g is the acceleration due to the gravity
v is the velocity of the child
thus,
at halfway down, h = = 8 m
therefore,
34.9 × 9.81 × 8 =
or
v = 12.528 m/s
b)
at three-fourth way down
height = = 12 m
thus,
loss in potential energy = gain in kinetic energy
34.9 × 9.81 × 12 =
or
v = 15.344 m/s
Answer:
Divergent plate margins
Explanation:
Divergent plate margins are constructive zones on the surface of the earth. They are constructive in the sense that new materials are brought to the surface from within the crust.
An example of such is the mid-altlantic ridge. Here as two plates pull apart, new melts up-wells and finds a way to get to the surface where they cool and solidify.
Answer:
14days, after registration
Explanation:
When you move into new jeey from another state you must have your vehicle inspected within ___.
answer: 14days after registration. To register a vehicle in New Jersey, one must have the following:
A valid driver license
A valid probationary license or a validated New Jersey Permit
Valid Insurance
Vehicle registration cards
Vehicles are inspected every two years, and five years for a new vehicle. There are checklist used by the inspector to ascertain the conditions of the vehicle and ensure if it is road worthy. Inspection are carried out to reduce road accidents which can endanger the life of the driver and other road users.
If the track has circumference c miles, then and the car's speeds are x and y mi/s, then since time = distance/speed,
<span>In the same direction, the slow car has a "lead" of 1 mile which the faster car has to make up. </span>
<span>1/(y-x) = 120 </span>
<span>1/(x+y) = 30 </span>
<span>120(y-x) = 30(x+y) </span>
<span>120y-120x = 30x+30y </span>
<span>90y = 150x </span>
<span>y = 5/3 x </span>
<span>1/(x + 5/3 x) = 30 </span>
<span>8/3 x * 30 = 1 </span>
<span>80x = 1 </span>
<span>x = 1/80 mi/sec = 45 mph </span>
<span>y = 75 mph</span>
