A = (Vf-Vi) / t,
a = (6-0)/3 = 2m/s^2,
F = ma = 2 * 2 = 4N
Decreases density because gases have less density than liquids
Answer: m = 0.4 kg
Explanation: Momentum is the product of mass and velocity also expressed in this equation:
p = m x v
Derive to find m
m = p / v
= 10 kg•m/s / 25 m/s
= 0.4 kg
Answer:
The object distance is 92 cm.
Explanation:
let v be the image distance and h be the height of the image, let u the be the object distance and H be the height of the object.
then, the magification of the mirror is given by:
m = -v/u and m = h/H
so, -v/u = h/H
u = -v×H/h
= -(-4.6)×(82)/(4.1)
= 92 cm
Therefore, the object distance is 92 cm.
The answer is that He is gonna struggle
