Answer: 6.175 km
Explanation:
from the question, we have the following
velocity of the automobile = 95 km/g
velocity of the train = 75 km/h
length of the train = 1.30 km
since the automobile and the train are moving in the same direction, we need to find the velocity of the car relative to the train which will be their difference in speed = 95 - 75 = 20 km/h
we need to find the time it takes the automobile to overtake the train using the formula time = distance / speed , with the distance being the length of the train.
time (t) = 1.3 / 20
= 0.065 hour
now we can find the distance traveled by the automobile using the the time taken for it to overtake the train and the speed of the automobile.
therefore, distance = speed x time
distance = 95 x 0.065 =6.175 km
Answer:
the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.
Explanation:
Given;
length of the wire, = 34.9 m
length of solenoid, L = 0.24 m
radius of the solenoid, r = 0.051 m
current in the solenoid, I = 11.0 A
The number of turns of the wire is calculated as follow;
The strength of the magnetic field inside the solenoid is calculated as follows;
Therefore, the strength of the magnetic field inside the solenoid is 6.278 x 10⁻³ T.
Answer:
Your answer will be A
Explanation:
The Pacific Ocean is very cold, and a cup of hot chocolate is very hot (hence the name). More thermal energy entails a higher temperature, therefore the cup of hot chocolate has more thermal energy and a higher temperature.
Answer:
Explanation:
1. All screws give the same M.A.
False - it depends on screw size and threads
2. A screw does its job by moving.
True - as far as screw as a machine
3. A screw with more threads has a smaller M.A.
False - more threads increase output force i.e. higher MA
4. Screws can be used to move things. *
True
