A 3 kg rubber block is resting on wet concrete. The coefficient of static friction is 0.3. What is the minimum force that must be applied to the block to make the block begin to accelerate?
Answer:
You would have to find the friction force of the rubber block which would be found with the equation of Normal force (mass*gravity) times cooeficient of friction which would give 8.82 N for the amount of friction and because you need more force than 8.82 N (assuming gravity is 9.8)
We need to find the frictional force of the rubber block. This is the normal force (mass × gravity) multiplied by the coefficient of friction, which gives us a friction quantity of 8.82N. This is because it requires a force greater than 8.82N (Gravity is 9.8)
What is coefficient of friction?Mathematically, = F/N, where F represents the frictional force and N represents the normal force. Because F and N are both measured in force units (such as Newtons or Pounds), the coefficient of friction is dimensionless.The friction coefficient is the ratio of the frictional force resisting movement of two contacting surfaces to the normal force pushing the two surfaces together.Both F and N are measured in units of force (such as Newtons or Pounds), so the coefficient of friction is dimensionless. The coefficient of friction has different values for static friction and sliding friction.In stiction, the frictional force resists the force applied to the object and the object remains stationary until the force of stiction is overcome. In kinetic friction, the frictional force opposes the motion of an object.To learn more about coefficient of friction, refer to:

Carol pushes down at an angle of 30 degrees from the vertical on a 10.0 kg wood crate causing the crate to move across a wood floor at a constant velocity of 2.0 m/s. How much force does Carol exert on the crate? (μs = 0.5 and μk = 0.2)
Answer:
F = 39.2 N
Explanation:
Since, the object is in uniform motion. Therefore, the frictional force on object will be:
Frictional Force = μk N = μk mg
where,
μk = coefficient of kinetic friction = 0.2
m = mass of crate = 10 kg
g = 9.8 m/s²
Therefore,
Frictional Force = (0.2)(10 kg)(9.8 m/s²)
Frictional Force = 19.6 N
The horizontal component of force must be equal to this frictional force to continue the uniform motion:
F Sin 30° = 19.6 N
F = 19.6 N/Sin 30°
F = 39.2 N
What is the net force required to accelerate a 1.1 kg box at a rate of 2.8
m/s??
Answer:
Fnet = 13.86N
Explanation:
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
Mathematically, net force is given by the formula;
[tex] Fnet = Fapp + Fg[/tex]
Where;
Fnet is the net force Fapp is the applied forceFg is the force due to gravitationGiven the following data;
Mass = 1.1kg
Acceleration = 2.8m/s²
To find the applied force;
[tex] Fapp = ma[/tex]
Substituting into the equation, we have;
[tex] Fapp = 1.1 * 2.8[/tex]
Fapp = 3.08N
To find the gravitational force;
We know that acceleration due to gravity, g = 9.8m/s²
[tex] Fg = mg[/tex]
Substituting into the equation;
[tex] Fg = 1.1 * 9.8[/tex]
Fg = 10.78N
To find the net force;
[tex] Fnet = Fapp + Fg[/tex]
Substituting into the equation, we have;
[tex] Fnet = 3.08 + 10.78[/tex]
Fnet = 13.86N
Therefore, the net force required is 13.86N

calculate the value of net force acting on given body?5N acting towards right & 15N force acting towards left on the brick.(draw fbd)
please help!!!!!
Answer:
-10N to the left.
Explanation:
The net force on a body is the single force that represent all the forces acting on a body.
Let the right direction be positive
Let the left direction be negative
Force acting to the right = 5N
Force acting to the left = -15N
Net force = 5N + (-15N) = -10N
The net force will be directed -10N to the left.

The motion of a car on a position time graph is represented with a horizontal tine What does this indicate about the car's motion?
Answer:
Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.
The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.
A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.
In this chemical reaction, one or more atoms replaces a part of a
compound.

synthesis
decomposition
combustion
replacement
neutralization
Explanation:
If there are more reactants than products, it is a synthesis reaction. If oxygen is a part of the reactant, it is a combustion reaction. If one ion replaces another, it is a single replacement reaction. If there are two compounds in a reactant where cations switch, it is a double replacement reaction.

Describe the importance that keystone species have in the environment. What would happen if these species disappeared? How would it affect the local ecosystems?
Answer:
See the answer below
Explanation:
The keystone species of an environment are those species of organisms that are highly influential to the functioning of the ecosystem without whom the ecosystem would be drastically affected, lose its structure, or cease to exist totally.
The influence of keystone species in an environment is disproportionately high when compared to their population in the environment. If keystone species disappeared from an environment, such an environment will find it difficult to perform ecosystem functions with an entirely different structure. In some cases, the ecosystem might cease to exist in its entirety because the species that hold it together are no longer present.
When a wire moves through a magnetic field, an electric current is produced in the wire. Why does this phenomenon occur?
Answer:
The negative charges and positive charges in the wire are pushed in the opposite directions by the magnetic field .
Explanation:
Hope this helps
When a wire moves through a magnetic field, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.
What is electromagnetic induction?A magnetic field is a region in space where a magnetic force can be detected, so when a wire moves through a magnetic field, the magnetic force exerted on the wire generates a voltage, and the voltage creates an electric current in the wire. This electromagnetic induction phenomenon occurs because of the movement of charged particles within the wire, and this phenomenon can be explained by Faraday's Law of Electromagnetic Induction.
Hence, an electric current is produced in the wire, and the phenomenon to which this is referring is called electromagnetic induction, as presented in option A.

Water waves with a frequency of 4.5 Hz and a wavelength of 2.0m are traveling across a small harbor that is 200 m wide. How long does it take the waves to travel from one side of the harbor to the over?
Answer:
22.2 seconds
Explanation:
recall that for a regular wave
v = fλ
where v = wave velocity (we need to find this to solve the next part)
f = frequency = 4.5 Hz
λ = wavelength = 2.0m
Substituting these into the equation above,
v = fλ
v = (4.5)(2)
v = 9.0m/s
Also recall that Distance travelled = velocity x time
in our case, we found velocity above (= 9.0 m/s) and the distance across the harbor is given as 200m, hence
Distance travelled = velocity x time
200 = 9.0 x time
time = 200/9.0
time = 22.2 seconds
