TRUE or FALSE? If a moving object experiences an unbalanced force, then the
object will have an acceleration that is in the same direction as the unbalanced
force.
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...

What tools can you use for measuring mass?
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.

A hotwheels car is rolled from 0.72 meters to the 1.51 meter mark. What is the displacement of the toy car?
(do not enter units into your answer in canvas)
Answer:
it is d]
Explanation:
The displacement of the toy car will be 0.79 meters.
What is displacement?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.

A giraffe, standing 6.00 m tall, bites a branch off a tree to chew on the leaves
and lets the branch fall to the ground. How long does it take the branch to hit
the ground?
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.

Derived units are derived from these 7 base units. Derived units are dependent on the base units and are not independent of each other. ... Mass has SI units of kg, distance is measured in m and t has the SI unit of second. Thus, SI unit of force is kg.
Pam is driving a car, and Dave is riding in the front passenger seat. Both are wearing seatbelts. Pam crashes head-on into a concrete barrier driving 50 kph. Assuming that Dave's mass is 1.5 times that of Pam, which statement below describes the force experienced by Dave?
А Dave experiences 3 times the force that Pam experiences.
B Dave experiences 1.5 times the force that Pam experiences.
C Dave experiences the same force as Pam. D Dave experiences half the force that Pam experiences.
Answer:
Option (B).
Explanation:
Given that,
Speed of Pam is 50 km/h
Force acting on an object is given by: F = ma
Pam is driving a car, and Dave is riding in the front passenger seat. Both are wearing seatbelts. As Dave's mass is 1.5 times that of Pam. It means that Dave experiences 1.5 times the force that Pam experiences.
Hence, the correct option is (B).

Describe all of the forces acting on the ice cream in the root beer float. Relate these forces to the fact that the ice cream is floating
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.

A rope is used to pull a 4.0 kg bucket of water upwards out of a deep well with an applied force 45 N. If starting from rest, what speed will the bucket have after experiencing this force for 2 seconds?
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!
How do you line up vectors so you can add them?
Answer:
The head-to-tail method of adding vectors involves drawing the first vector on a graph and then placing the tail of each subsequent vector at the head of the previous vector. The resultant vector is then drawn from the tail of the first vector to the head of the final vector.
Explanation:
A satellite in space has a mass of 252 kg. The engines on it provide a net force of 6.81×10-3 N. How long will it take for this satellite to go from rest to a final velocity of 262 m/s forward?
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 .

In studies about new medicines, researchers usually give one group of patients the medicine that is designed to treat an illness. They give another group of patients a placebo, which is taken the same way as the medicine but does not actually contain the ingredients of any medicine. Different medicines are tested in different experiments, but the placebos usually contain the same non-medical ingredients. If both groups of patients are healed, then researchers cannot be sure whether the medicine caused improvement, but if the group given the medicine is healed while the group given the placebo remains ill, researchers can conclude that the medicine causes the illness to go away.
IN MEDICAL EXPERIMENTS, WHICH GROUP RECEIVES PLACEBOS?
A.the experimental group
B.the control group
C.both the experimental and control groups
D.neither the experimental nor control group
Answer:
B=the control group
Explanation:
Answer:
B
Explanation:
see attached photo below!
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.
You hang a book bag on a spring scale and place the bag on a platform scale so that the platform scale reads 29.7 N and the spring scale reads 17.6 N.
Hello. This question is incomplete. The full question is:
You hang a book bag on a spring scale and place the bag on a platform scale so that the platform scale reads 29.7 N and the spring scale reads 17.6 N.
What is the magnitude of the force that Earth exerts on the bag?
Answer:
47.3 N
Explanation:
the entire system shown in the question above is at rest. Which greatly facilitates the calculation that we must do. In this case, to measure the magnitude that the force of the earth has on the backpack, you only need to add the two forces that you already know in the system.
In that case, it would be, you should calculate:
F= 29.7 N+ 17.6 N
F= 47.3N
A person is walking from the front of a train toward the back of a train at a constant velocity of 3 mph. The train is moving forward at a velocity of 20 mph. What is the velocity of the walking person relative to the land outside the train?
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.

What's the answer to this question?
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.
