Answer:
45
Explanation:
because the equation for speed is distance divided by time! hope that helps gave a nice day!
E = 1/2 m v^2
108000m /3600 = 30m/s
E = 1525 * 0.5 * 30 = 22875 J
Answer and Explanation:
We know that resistance
from the given equation of resistance it is clear that resistance depends on resistivity length and area of the material but we can not change the length because it is given that the length must be 2.5 cm long.
So we can do two two things to reduce the resistance
- increase the cross sectional area
- decrease the resistivity of the material
Answer:0.507m
To answer this question, you need to know how to calculate a cube volume. Cube volume is calculated by multiplying the length^3, make its unit become cubic meter.
In this case we know the volume is 130L and asked how long is the length in meter. Then you need to convert the liter into m3. The calculation would be:
V=R^3
130L= R^3
R= 3<span>√(130m3/1000)
R= 5.065797/10 m
R= 0.506579m
Rounded up to 0.507m</span>
