Answer:
1.04%
Explanation:
Given that,
The power of drill = 3.5 kW = 3500 W
Transferred kinetic energy = 5000 kJ during 15 seconds of use.
We need to find the percentage efficiency of the drill. It can be given by :
Where
Po and Pi are output and input powers.
So,
So, the percentage efficiency of the drill is 1.04%.

Took a a test and got it correct .... ——-The solubility curve for a gas would start higher and curve downwards as temperature increased
Answer:
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of the incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface).
1 inch = 2.54cm. 11*2.54 = 27.94cm. You would use multiplication. Hope this helps!! Can I get brainliest pls
