Answer:
165 minutes
Explanation:
We can break the numbers into prime numbers
15 = 3 * 5
33 = 3 * 11
55 = 5 * 11
The shortest time that must pass before they are all together again would be the least multiple that is divisible by all 3 number, which is
3 * 5 * 11 = 165
Hence after 165 minutes the 3 cars should all meet together again.
Answer: R = V / I
Explanation:
P = VI (power = voltage x current)
Ohm's Law tells us that V = IR.
Substitute IR for V in the first formula: P = (IR)I = I 2 R.
Rearrange to solve for resistance: R = P / I 2.
In a series circuit, the current across one component is the same as the total current. This is not true for a parallel circuit.
Answer:
- The separation will be spacelike.
- The first event can't cause the second event, as there exist an frame of reference in which both happens at the same time, in different positions, so, if there were causally connected, it will imply an instant connection, this is faster than light.
Explanation:
We can define the separation between two events (using the + - - - signature) as :
where the separation will be lightlike if is equal to zero, timelike if is positive and spacelike if is negative.
For our problem
So the separation will be spacelike, and the first event can't cause the second event, as there exist an frame of reference in which both happens at the same time, in different positions, so, if there were causally connected, it will imply an instant connection, this is faster than light.
Answer:
Explanation:
a) The net force on the box in vertical direction:
Fnet=Fg−f−Fp *sin45 °
here Fg is the gravitational force .f is the force of friction and , Fp is the pushing force.
Fnet=ma
ma=Fg−f−Fp *sin45 °
a=
=0.24 m/s²
Vf =Vi +at
=0.48+0.24*2
Vf=2.98 m/s
b)
Fnet=Fg−f−Fp *sin45 °
=Fg−0.516Fp−Fp *sin45 °
=30-1.273Fp
Fnet=0 (Because speed is constant)
Fp=30/1.273
=23.56 N
