Complete Question:
The momentum of an object is determined to be 7.2 × 10-3 kg⋅m/s. Express this quantity as provided or use any equivalent unit. (Note: 1 kg = 1000 g).
Answer:
7.2 gm/s.
Explanation:
Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.
Mathematically, momentum is given by the formula;
Given the following data;
Momentum = 7.2 * 10^-3 kgm/s
1 kg = 1000 g
Substituting the unit in kilograms with grams, we have;
Momentum = 7.2 * 10^-3 * 1000 gm/s
<em>Momentum = 7.2 gm/s. </em>
Answer:
36.74 N
Explanation:
Given that:
A crate of oranges with a total mass (m) = 6.7 kg
angle θ = 0.7 rad
angle θ =
angle θ = 40°
acceleration = 4.2 m/s²
Given that:
T cosθ = ma
T cos 40° = 6.7 × 4.2
T =
T =
T = 36.74 N
Thus, the tension in the rope = 36.74 N
Answer:
0.21 lunar month
Explanation:
the radius of moon = r₁
time period of the moon = T₁ = 1 lunar month
The radius of the satellite = 0.35 r₁
Time period of satellite
The relation between time period and radius
now,
T₂ = 0.21 lunar month
hence, the time period of revolution of satellite is equal to 0.21 lunar month
