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.
Answer:
B
Explanation:
the river is caused by weathering and erosion is the breaking down of rocks
Answer:
240.59 N
Explanation:
We are given that
Mass per unit length=m/l=
Fundamental frequency,f=146.8 Hz
Tension=T=82.4 N
Mass per unit length=
We have to find the tension.
Velocity,v=
New tension,T'=
Hence, the string should have tension 240.59 N so that its fundamental frequency is 146.8 Hz
Answer:
Explanation:
The first part of question is about the height of the rock from which it falls and hit the ground with speed of 11 m/s. Lets find out that height.
We will use the formula,
As the initial velocity of the rock was zero.
Now we have to find the height from which the rock should be dropped and it's speed on hitting the ground should be 22 m/s.
Again we will use the same formula, same calculation but the value of velocity now should be 22 m/s.
The complete question is;
James Joule (after whom the unit of energy is named) claimed that the water at the bottom of Niagara Falls should be warmer than the water at the top, 51 m above the bottom. He reasoned that the falling water would transform its gravitational potential energy at the top into thermal energy at the bottom, where turbulence brings the water almost to a halt. If this transformation is the only process occurring, how much warmer will the water at the bottom be?
Answer:
Water becomes warmer by a temperature of ΔT = 0.119 K
Explanation:
If we assume that gravitational kinetic energy will be converyrf into thermal enrgy, we will have;
Q = U
So, m•c_w•ΔT = mgh
Where;
c_w is specific heat capacity of water with a value of 4184 J/Kg.K
ΔT is change in temperature indicating how warmer the water will be. Thus making ΔT the subject, we have;
ΔT = gh/c_w
So, ΔT = 9.8 x 51/4184 = 0.119 K
