Given: Mass m = 45 Kg: Density ρ = 2.7 Kg/m³
Required: Volume V = ?
Formula: ρ = m/V
V = m/ρ
V = 45 Kg/2.7 Kg/m³
V = 16.67 m³
Answer:
Explanation:
Time to cover first 100 km = 1 hour.
time remaining = 3.15 - 1 = 2.15 hour .
Time to cover next 42 km = 1 hour .
Time remaining = 2.15-1 = 1.15 hour.
Distance to be covered = 310 - 142
= 168 km
least speed needed = distance remaining / time remaining
= 168 / 1.15
= 146.08 km / h .
The largest transition metal is copernicium with 112 protons.
They need more oxygen to function, so gas exchange needs to increase
Answer:
(c) position
Explanation:
From the work-energy theorem, the workdone by a force on a body causes a change in kinetic energy of the body.
But, remember that the work done (W) by a force (F) on a body is the product of the force and the distance d, moved by the body caused by the force. i.e
W = F x d
This distance is a measure of the position of the body at a given instance.
Therefore, the work done is given by the force as a function of distance (or position).
