Answer:
80 seconds
Explanation:
40/.5 is equal to 40*2 which is 80 or in another way 1 second is 2 seconds is 1 m
Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.
B.
Weight is a measure of the amount of matter in an object, while mass is a measure of the force of gravity on the object.
C.
Mass is a measure of an object's inertial force, and weight is the force exerted by that object on other objects.
D.
Mass and weight are synonyms and ultimately describe the same principle.
Weight is a measurement of the object's gravitational pull, whereas mass is a measure of the amount of substance in the thing. The right answer is A.
Mass is a measure of a physical body's entire makeup. This term also measures inertia, or the body's resistance to acceleration when a net force is applied. The basic mass unit of the SI is the kilogram.
The weight of an object refers to the gravitational force acting on it. Weight is the term used in many widely used textbooks to describe the gravitational force acting on the object. The mass is a matter present and the weight is the force.
Therefore, the weight is a measurement of the object's gravitational pull, whereas mass is a measure of the amount of substance in the thing. The right answer is A.

Mass is the measure of how much matter an object has and remains constant regardless of location, while weight is the measure of the force of gravity acting on that object, which varies based on the gravitational environment.
Mass is a measure of the amount of matter in an object. It is a property that reflects how much space that object occupies in three-dimensional space. It remains constant regardless of where the object is.
On the other hand, weight is a measure of the force of gravity acting on the object. Weight can change based on the gravitational force of the environment; for example, an object weighs less on the moon than it does on Earth because the moon's gravitational force is less than Earth's.
So, the answer to your question is A. Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity on the object.

Answer: Here's my answer, I made it step-by-step so you can understand it! <3
Explanation:
To find the centripetal acceleration of the tip of the fan blade, we can use the formula for centripetal acceleration:
a = (v^2) / r
where:
a is the centripetal acceleration,
v is the linear velocity, and
r is the radius of the circular path.
Given that the fan completes 2 rotations every 1.0 second, we can find the angular velocity (ω) using the formula:
ω = (2π * n) / t
where:
ω is the angular velocity,
π is a constant (approximately 3.14),
n is the number of rotations (2),
and t is the time taken (1.0 second).
Substituting the values into the formula, we have:
ω = (2π * 2) / 1.0 = 4π rad/s
Next, we can calculate the linear velocity (v) using the formula:
v = r * ω
Substituting the given radius value (0.61 m) and the angular velocity we found earlier, we have:
v = 0.61 * 4π = 2.44π m/s
Finally, we can calculate the centripetal acceleration (a) using the formula:
a = (v^2) / r
Substituting the linear velocity and the radius, we have:
a = (2.44π)^2 / 0.61 = 5.88π^2 / 0.61 ≈ 96 m/s²
Therefore, the centripetal acceleration of the tip of the fan blade is approximately 96 m/s² (Option 4).
