Protons
electrons are negatively charged
neutrons are neutral
Answer
given,
ω₁ = 0 rev/s
ω₂ = 6 rev/s
t = 11 s
Using equation of rotational motion
The angular acceleration is
ωf - ωi = α t
11 α = 6 - 0
= 0.545 rev/s²
The angular displacement
θ₁= ωi t + (1/2) α t²
θ₁= 0 + (1/2) (0.545)(11)^2
θ₁= 33 rev
case 2
ω₁ = 6 rev/s
ω₂ = 0 rev/s
t = 14 s
Using equation of rotational motion
The angular acceleration is
ωf - ωi = α t
14 α = 0 - 6
= - 0.428 rev/s²
The angular displacement
θ₂= ωi t + (1/2) α t²
θ₂= 6 x 14 + (1/2) (-0.428)(14)^2
θ₂= 42 rev
total revolution in 25 s is equal to
θ = θ₁ + θ₂
θ = 33 + 42
θ = 75 rev
The relationship between mass m, volume V and density d is:
The silver has density
, and the mass of the piece of silver is
. Therefore we can calculate its volume using the previous formula:
Answer:
Distance = 150 meters
Explanation:
Given the following data;
Work done = 6,000 Joules
Force = 40 Newton
To find the total distance covered by the wheelbarrow;
Workdone = force * distance
Substituting into the formula, we have;
6000 = 40 * distance
Distance = 6000/40
Distance = 150 meters
Therefore, the total distance the wheelbarrow was pushed is 150 meters.
