Both positive work and negative work have meaning: Positive work follows when the force has a component parallel to the displacement. Positive work adds energy to a system. Negative work follows when the force has a component opposite or against the displacement.
The #1 answer would be meats and eggs. But, as a veggan, I present you with meatless protien-rich food!
1 - <u>Pea protein</u> (used in Beyond Meat, which tastes just like meat btw!)
2 - <u>Soy protein</u> such as tofu
3 - <u>Nuts</u>
4 - <u>Beans</u>! oml so many beans have MORE protien than meat!! ikr!?!?
may I have Brainliest pls =)
Answer:
The force exerted is 318.86 N
Explanation:
The force exerted by such a stream is calculated by multiplying the mass flow rate of water by the velocity of the stream of water.
mass flow rate = 21.4 kg/s
velocity = 14.9 m/s
Force exerted = 21.4 kg/s × 14.9 m/s = 318.86 kgm/s^2 = 318.86 N
Answer:
b)
Explanation:
Normal force, is always directed upward the surface over which is placed the object, and can adopt any value, as required to meet Newton's 2nd Law.
In this case, as the external force on the suitcase pulls upward, in order to counteract the influence of gravity, normal force is less than the weight of the suitcase, as follows:
F + Fn = m*g
⇒ Fn = m*g - F
So, the normal force is equal to the magnitude of the weight of the suitcase (m*g) minus the magnitude of the force of the pull (F) which is the same expressed by the statement b.
