How many atoms are in something determines it "mass"
Non metal because if the wire was unknowingly live, it could shock him and the current would travel through metal gloves.
It is called a conclusion
Answer: The air pressure would build up resulting in a high air density.
Explanation: Heat energy builds up air pressure. And if you surround it with bubble wrap, that air pressure will have nowhere to release to. And so because of that, high air density occurs.
Answer:
255.09 m
Explanation:
Using
H = U²sin²θ/2g.................. Equation 1
Where H = maximum elevation, U = initial velocity, θ = Angle of projectile, g = acceleration due to gravity.
Given: U = 110 m/s, θ = 40°, g = 9.8 m/s².
Substitute into equation 1,
H = 110²sin²40/(2×9.8)
H = 12100(sin²40)/(19.6)
H = 12100(0.4132)/19.6
H = 255.09 m.
Hence the maximum elevation achieved by the projectile = 255.09 m
