Answer:
The darts hit very different areas of the board.
Explanation:
Density = (mass) / (volume)
4,000 kg/m³ = (mass) / (0.09 m³)
(4,000 kg/m³) x (0.09 m³) = mass
mass = 360 kg
force of gravity = (mass) x (acceleration of gravity) = (360 kg) x (9.8 m/s²) = (360 x 9.8) kg-m<span>/s² </span><span>= </span>3,528 newtons .
Answer:
if the mass of both objects is doubled, then the force of gravity between them is quadrupled and so on
Answer:
7.4 cm
Explanation:
K = 2.17 x 10^3 N/m
m = 4.71 kg
v = 1.78 m/s (It is maximum velocity)
The angular velocity
ω = 24 rad/s
Maximum velocity, v = ω x A
Where, A be the maximum displacement
1.78 = 24 x A
A = 0.074 m = 7.4 cm
Answer: 55m
Explanation:
Given the following :
Driving speed = 90km/hr
Inattentive period (time) = 2.2s
Distance during inattentive period =
(driving speed * time)
Converting driving speed from km/hr to m/s
1000m = 1km
3600s = 1hour
Therefore,
90km/hr = (90 * 1000) / 3600
90km/hr = (90000)/ 3600 = 25m/s
Therefore ;
Distance during inattentive period =
(driving speed * time)
Distance during inattentive period = (25m/s × 2.2s) = 55m
Distance traveled during inattentive period is 55m
