Answer:
The acceleration the ball gets = 30 m/s²
Explanation:
The given parameters are;
The mass of the first ball that hits an object, m₁ = 0.35 kg
The mass of the object hit by the ball, m₂ = 7 kg
The acceleration given to the second object, a₂ = 1.5 m/s²
Let the a₁ represent the acceleration the ball gets
Newton's third law states that action and reaction are equal and opposite, therefore, the force exerted on a body A by a body B is equal to the force exerted on the body B by the body A;
Therefore, we have;
The force exerted on the object, F₂ = m₂ × a₂ = 7 × 1.5 = 10.5 N
The force the ball exerts on the object = F₁ = m₁ × a₁ = 0.35 × a₁
By Newton's third law, F₁ = F₂, which gives;
m₁ × a₁ = m₂ × a₂
0.35 × a₁ = 10.5
a₁ = 10.5/0.35 = 30
The acceleration the ball gets = a₁ = 30 m/s².
Answer:
The breast bone is anterior to the spine. The collarbone is superior to the shoulder blade. The elbow is proximal to the wrist. The navel is distal to the chin.
Explanation:
The spine, also known as the backbone, is posterior to the breast bone.
The collarbone (also known as the clavicle), which is part of the shoulder girdle, lies superior in position to the shoulder blade (also known as the scapula).
The elbow is the joint between the arm and the wrist. it is proximal to the wrist.
The navel, located on the anterior abdominal wall, is distal to the chin that is part of the face.
Answer:
1. Urea, (d)Fertilizer
2. Combines, (c) Harvesting and threshing
3. Silos, (b) Storage of grains
4. Seed drills, (a) Sowing seeds
5. Irrigation, (f) Sprinklers
6. Tilling, (e) Preparation of soil
Explanation:
1) Urea is a widely used and important fertilizer in the agricultural industry
2) The combine harvester combines three categories of harvesting grain drops such as threshing reaping and winnowing
3) Silos are used to store grains
4) A seed drill is a seed planting mechanism for burying seeds to a particular depth during seed planting
5) Irrigation is the application of required volume of water to plants
6) Tilling is the digging, turning, and staring operations meant to prepare the soil.
