Engineering controls could involve altering the weight of the products, adjusting the heights of the work surfaces, or getting lifting equipment. Administrative controls are workplace policies, practices, and processes that reduce the likelihood of risky situations for employees.
<h3>What are Engineering controls?</h3>
- Engineering controls are methods for preventing dangerous situations for workers by erecting a barrier between them and the danger or by ventilating the area to remove any hazardous materials.
- Instead of depending on employee behavior or mandating that employees wear safety gear, engineering controls entail making physical changes to the workplace itself.
<h3>What is Administrative controls?</h3>
- Administrative controls are policies, procedures, shift designs, or training that reduce the threat of a hazard to a person.
- Typically, administrative controls aim to alter people's behavior (such as that of manufacturing workers) rather than eliminating the real risk or provide personal protective equipment (PPE).

Answer:
Maximum height, h = 10 m
Explanation:
It is given that,
Mass of golf ball, m = 45 g = 0.045 kg
The ball comes down on a tree root and bounces straight up with an initial speed of 14.0 m/s.
We need to find the height the ball will rise after the bounce. It is based on the conservation of energy such that,
h is maximum height raised by the ball
So, the ball will raised to a height of 10 meters.
Mercury is the closest planet to the sun.
Venus is second planet. Venus has no moons.
Earth is the third planet. This is the only planet that is known to inhabit life.
Mars is the fourth planet. Mars is called the "red planet" and has two moons.
Jupiter is the fifth planet in our solar system. Jupiter is the biggest planet in our solar system.
Saturn is the sixth planet. It has 31 moons.
Uranus is the seventh planet. It is a greenish-blue planet.
Neptune is the eight planet. On Neptune, temperatures stay colder than -350 Fahrenhiet.
Pluto is no longer a planet, but if you weighed 100 pounds on Earth, then you would weight 7-8 pounds on Pluto. But your mass would be the same.
Answer:
Buffy weigh's 28.39 kg
Explanation:
Given;
mass of Buffy and wagon, M = 10.4 kg
final velocity of Buffy - wagon system, v = 3.4 m/s
Buffy's velocity relative to the ground, u₁ = 1.7 m/s
Wagon's velocity relative to the ground, u₂ = 8.04 m/s
Buffy's velocity = 1.7 - 3.4 = - 1.7 m/s
Wagon's velocity = 8.04 - 3.4 = 4.64 m/s
Apply the principle of conservation of linear momentum;
1.7 x m = 4.64 x 10.4
where;
m is mass of wagon
1.7 m = 48.256
m = 48.256 / 1.7
m = 28.39 kg
Therefore, Buffy weigh's 28.39 kg
