Answer:
I am pretty sure it's E because it splits through every layer
Answer:
The pectoralis major, latissimus dorsi, deltoid, and rotator cuff muscles connect to the humerus and move the arm. The muscles that move the forearm are located along the humerus, which include the triceps brachii, biceps brachii, brachialis, and brachioradialis.
Answer: 1) Cold water is more dense and will sink in room temperature water.
2) Cold salty water is denser than warm freshwater.
3) Temperature is the measure of heat. Density is the measure of how closely any given entity is packed or it is the ratio of the mass of the entity to its volume.
4) Salinity and density share a positive relationship. As density increases, the amount of salt in water-also known as salinity- increases.
Answer:
423m/s
Explanation:
Suppose after the impact, the bullet-block system swings upward a vertical distance of 0.4 m. That's means their kinetic energy is converted to potential energy:
where m is the total mass and h is the vertical distance traveled, v is the velocity right after the impact at, which we can solve by divide both sides my m
Let g = 9.81 m/s2
According the law of momentum conservation, momentum before and after the impact must be the same
where 
are the mass and velocity of the bullet before the impact, respectively.
are the mass and velocity of the block before the impact, respectively, which is 0 because the block was stationary before the impact
Answer:
The acceleration of the runner is 0.25 m/s²
Explanation:
Given;
distance covered by the runner, d = 200 m
time of motion, t = 10 s
initial velocity of the runner, u = 0 (he started standing still)
final velocity of the runner, v = 36 km/h = 10 m/s
Therefore, to achieve the final speed of the runner, his acceleration is calculated as follows;
v² = u² + 2as
10² = 0 + (2 x 200)a
100 = 400a
a = 100/400
a = 0.25 m/s²
The acceleration of the runner is 0.25 m/s²
