Answer:
12N
Explanation:
Force = mass * acceleration.
6 * 2 = 12
Taking into account the Newton's second law, the force required to accelerate a 6 kg bowling ball at 2 m/s² forward is 12 N.
In first place, acceleration in a body occurs when a force acts on a body. There are two factors that influence the acceleration of an object: the net force acting on it and the mass of the body.
Newton's second law states that this force will change the speed of an object because the speed and / or direction will change. These changes in velocity are called acceleration.
So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object.
Mathematically, Newton's second law is expressed as:
F= m×a
where:
F = Force [N] m = Mass [kg] a = Acceleration [m/s²]In this case, you know:
F= ? m= 6 kg a= 2 m/s²Replacing:
F= 6 kg× 2 m/s²
Solving:
F= 12 N
Finally, the force required to accelerate a 6 kg bowling ball at 2 m/s² forward is 12 N.

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:
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...

Mrs. Franklin loves teaching science and thinks about it all the time. While walking one day, she steps on a warm, fresh piece of used gum. The gum flattens and sticks to her shoe. When she lifts her foot, she sees long strings of gum between her shoe and the sidewalk. She thinks, “What a great demonstration of the properties of metals!” What properties of metals would Mrs. Franklin most likely teach about with this demonstration?

Calculate the average force that must be exerted on a 0.145 kg baseball in order to give it an acceleration of 130 m/s^2. (round to the nearest whole number)
Answer:
18.9 N or 19 N rounded
Explanation:
m = 0.145 kg
a = 130 m/s^2
F = ma = (0.145 kg)(130 m/s^2) = 18.9 N
Magnitude of the average force
F = 18. 9 N
There are three laws of motion that are given by Newton in order to study the Force and Inertia on the objects in motion or rest.
Newton's First Law defines Inertia
The second law gives the definition of Force
Third law states about action reaction pairs on the objects interacting with each other.
According to Newton' s second law of motion we can write equation (1)
[tex]\rm F = ma.....(1) \\\rm Where\; F = Net\; unbalanced\; external\; force\; acting\; on \; the \; system \\\\a = acceleration \; of \; center\; of\; mass\\[/tex]
Now according to the question
we can write
Mass of the baseball = 0.145 kg
Acceleration of the baseball = 130 [tex]m/s^2[/tex]
Magnitude of the average force can be find out by putting in equation (1)
F = ( 0.145 ) ( 130) = 18.85 N [tex]\approx[/tex] 18. 9 N

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

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.

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 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.

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.
