Answer:
999.23 km/h
Explanation:
We can use the formula for average speed as "Distance divided time" to solve the problem.
Let's start by writing the time in hours: 4 h and 20 min is the same as 4 hours + 1/3 of an hour = 13/3 of an hour
Now we use this number in the quotient for average speed:
Average speed = 4330 km / (13/3) h = 12990 / 30 km/h = 999.23 km/h
The distance between Earth and Sun is about 0.0000038 times
the distance to the next nearest star.
(The next nearest star is about 265,300 times as far from us as
the sun is.)
The distance between Earth and Sun is about 0.000000000000000000068
times the distance to the next nearest galaxy.
(The next nearest galaxy is about 14,700,000,000,000,000,000 times
as far from us as the sun is.)
Answer:
1 and 3
Explanation:
<u>1 and 3 </u>
Increasing coils increases strength
COOLING the wire would increase current flow and strength of magnet
Adding an iron core will definitely increase the strength of the electromagnet
B-the temperature at which condensation occurs
sorry if I’m wrong but thats what I remember what few point was
Answer:
36 cm
Explanation:
Sum of moments about the fulcrum:
∑τ = Iα
3 (-d) + 2 (90 − d) = 0
-3d + 180 − 2d = 0
180 − 5d = 0
d = 36
