A because the normal force always acts perpendicular and away from the surface an object is in contact with.
Answer:
Time taken to cover the distance 11.45 s.
Explanation:
The given parameters:
Initial Velocity(u)=24 m/s
Acceleration (a)=8
Distance or Displacement(s)=800 m
Displacement or Distance is equal in the above because it travels in a straight line.
We have to apply Second Equation of Motion,
s=ut+
800=24t + 4
200=6t +
+ 6t - 200=0
Solving, the quadratic equation to find out the roots, we get that the possible values of t will be 11.45 s and a negative value.
The negative value will be neglected as time cannot be negative.
Hence, the time taken is 11.45 s.
Answer:
The velocity from the personne flying over the island is
Explanation:
The island experiences a contraction of length, because the person who measures it, sees as if the island moves with a speed v. Relativistic Law, for an object with a velocity v and a length at rest Lo, and a length L at a velocity v :
The wording of the choices is really unclear. With two resistors in parallel,
here's the situation:
-- The voltage across each resistor is the same as the voltage across
the other one. If the parallel combination is connected to the battery,
then the voltage across each resistor is the full battery voltage.
-- The current through each resistor is (V) / (the resistance of that resistor).
That's the same current as would flow through that resistor if the other one
were not there.
-- As long as the battery or other power supply holds out, neither of these
quantities changes.
Can you match this situation to one of the choices listed ?
It looks to me as if choice 'C' is the one that's most likely
trying to say this.
Newton should be the answer.
