Answer:
170 N
Explanation:
The following data were obtained from the question:
Mass (m) = 20 Kg
Angle (θ) = 30°
Acceleration due to gravity (g) = 9.8 m/s²
Weight (W) =?
The perpendicular component of the weight can be obtained by using the following formula:
W = mg × Cosθ
W = 20 × 9.8 × Cos 30
W = 196 × 0.866
W = 169.7 ≈ 170 N
Therefore, perpendicular component of the weight is 170 N
The masses are equal.
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
I hope that this helps you!
Answer:
This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you.
