Answer:
<u>B. East of NYC</u>
Explanation:
We can make this conclusion because for one reason New York City is the Northern Hemisphere, and according to the Coriolis effect <em>when objects in the Northern Hemisphere travel long distances above the ground, </em><em>they will be deflected to the right </em>as a result of earth's rotation.
Hence, going by the map of New York on the Northern Hemisphere, <em>when the (object) flight is deflected to the right, for someone in NYC it will indicate a </em><em>shift to the east of NYC</em><em> </em>since the pilot failed to take the Coriolis Effect into account.
Explanation:
If you wrap some of the wire around the nail in one direction and some of the wire in the other direction, the magnetic fields from the different sections fight each other and cancel out, reducing the strength of your magnet
Answer:
8962.5 N
Explanation:
From fundamental kinematics equations, acceleration, a is given by
where v is final velocity, u is initial velocity and t is time
We also know that force is a product of mass and acceleration of an object and substituting
in the formula F=ma we obtain
where m is the mass of the body

Therefore, the force is 8962.5 N
Answer:
0.695s
Explanation:
From Hooke's law, the restoring force is given has
F = -ky .......1
Where F is the force, y is the spring displacement and k force constant of the spring.
Also recall,
F=mg ............ 2
Where m is the mass of object, g is the acceleration due to gravity.
Equating 1 and 2
Ky = mg
Given that g=9.8m/s2 , y is 3.4cm and g is 8g
K×3.4/100m =8/1000kg × 9.8m/s2
K= ( 0.008kg × 9.8m/s2 ) ÷ 0.034
K= 0.0784÷0.035
K=2.24N/m
Mass ofvthe second object is 25g =0.025kg
Period of oscillation T
T=2π√m/k
T=2×3.142√0.025/2.24
T=6.284√0.0111
T=0.659seconds
Answer:

Explanation:
As we know that initial angular speed of the tub was zero and then it increases uniformly to 4 rev/s in t = 6.00 s
so we will have




Now when the tub will comes to rest uniformly after opening the lid in time interval of t = 15 s
then we have




Now total angular displacement of the tub is given as



so number of revolutions is given as
