Answer:

With a balance

Explanation:

Such as an electronic balance and a triple beam balance

The tools that one can use for measuring mass are Balance or Scale, Weighing Machine, Triple Beam Balance, etc.

A balance or scale is a frequently used tool for precisely measuring mass. Usually, it consists of a pan or platform where the thing whose mass is being measured is set.

Weighing Machines: Weighing machines are electronic devices that measure mass and are frequently seen in homes and commercial settings.

Mechanical balance with three beams and movable weights, the triple beam balance has three beams.

Digital Kitchen Scale: When baking and cooking, digital kitchen scales are frequently utilised. They offer convenient and quick mass measurements for the constituents, usually presenting the results digitally.

Thus, these are only a few types of mass measurement equipment.

Answer:

it is d]

Explanation:

The displacement of the toy car will be 0.79 meters.

The shortest route between two points is displacement.

It is a vector quantity to be displaced. This suggests that it has a size and a direction, and that it may be thought of as an arrow pointing from one place to another.

Distance is never less than displacement; it must always be more than or equal to it.

Displacement can be zero if the starting and end point are the same.

According to the question, the Hot wheel car rolled from 0.72 meters to the 1.51-meter mark.

So, the displacement of the toy car will be :

⇒1.51-0.72

=0.79

Hence, the total displacement will be  0.79 meters.

Answer:

1.11 s.

Explanation:

From the question given above, the following data were obtained:

Height (H) = 6 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =.?

The time taken for the branch to hit the ground can be obtained as follow:

H = ½gt²

6 = ½ × 9.8 × t²

6 = 4.9 × t²

Divide both side by 4.9

t² = 6/4.9

Take the square root of both side

t = √(6/4.9)

t = 1.11 s

Therefore, it will take 1.11 s for the branch to hit the ground.

Answer:

0 m/s²

Explanation:

Velocity is the slope of the position vs time graph.  The graph is linear, so the velocity is constant.  Since the velocity is constant, the acceleration is 0.

Answer:

v = 22.5 m/s

Explanation:

The speed of the bucket can be found using the following equation:

[tex] V_{f} = V_{0} + at [/tex]

Where:

[tex]V_{f}[/tex]: is the final speed =?

[tex]V_{0}[/tex]: is the initial speed = 0 (starts from rest)

a: is the acceleration

t: is the time = 2 s

We need to find the acceleration, it can be found as follows:

[tex] F = ma [/tex]

Where:

F: is the force = 45 N

m: is the mass = 4.0 kg

[tex] a = \frac{F}{m} = \frac{45 N}{4.0 kg} = 11.25 m/s^{2} [/tex]

Now, the speed is:

[tex] V_{f} = V_{0} + at = 11.25 m/s^{2}*2 s = 22.5 m/s [/tex]

Therefore, the speed that the bucket will have is 22.5 m/s.

I hope it helps you!

Acceleration = (force) / (mass)

Acceleration = (6.81 x 10⁻³ N) / (252 kg)

Acceleration = 2.70 x 10⁻⁵ m/s²

Time = (change in v) / (acceleration)

Time = (262 m/s) / (2.70 x 10⁻⁵ m/s²)

Time = 9,703,704 seconds

That's  2,695.5 hours , or  112.3 mean solar Earth days .

Answer:

302129m

Explanation:

Using s= ut + 1/2at²

But u= 0

So

S= 1/2(3.1)(441.5)²

=302129m

Explanation:

This is the Galilean transformation.

V' = V - U   where want to find V' in the primed frame of reference.

The primed frame is moving at speed U = -20 relative to the train.

V = -3 is the speed of the person in the frame of the train.

Then V' = -3 - (-20) = 17 mph relative to the land outside the train.

Answer: Sample Response: The root beer exerts a force on all sides of the ice cream. These forces are all equal and cancel each other out. Gravity pushes downward on the ice cream. This can also be called the weight of the ice cream. Buoyant force pushes the ice cream upward. The ice cream floats because the buoyant force is greater than the weight of the ice cream.

Explanation:

True I guess

because if the force is balanced and there is no net force, the object will not accelerate and the velocity will remain constant...

Not sure

Answer:

The barometer is supporting 75 cm of Hg due to atmospheric pressure.

Since the manometer is open to air pressure, the gas pressure is supporting the air pressure plus the 30 cm of Hg.

So the "absolute" gas pressure is 75 + 30 = 105 cm of Hg.
