Answer:
Magnetic flux will be equal to
Explanation:
It is given radius of circular loop r = 0.10 m
Area of circular loop
Magnetic field B = 0.20 T
Angle between plane of loop and magnetic field
Magnetic flux will be equal to
So magnetic flux will be equal to
Answer:
An 8 kg sled mass moves in a straight line on a surface without horizontal friction at a certain point its speed is 4 m / s 2.50 m later its speed is 6 m / s using the work and energy theorem, determine the force acting on the sled assuming it is constant and acts in the direction of the sled movement
The force acting on the 8 kg sled has a value of 32 N.
Explanation:
We have initially look for the work that is applied to the sled, and this will be nothing more than the difference in kinetic energy from the end point to the initial, then:
ΔEc = Ec₂ - Ec₁
ΔEc = 0.5 * m * [V₂² - V₁²]
ΔEc = 0.5* 8 kg * [(6m / s) ² - (4m / s) ²]
ΔEc = 80 J
So, the work is 80 J, now we know that work is a relation distance and force , such that:
W = F * d
F = W / d
F = (80 J) / (2.50 m)
F = 32 N
Therefore, the force acting on the sled is 32 N.
Answer:
Higher mass or higher speed
Explanation:
Higher mass will require more force
F= ma if m goes up F goes up to stop in the same distance
The algebraic expression for the component of the normal force in the vertical direction is Force= product of mass and area.
<h3>
What is Force?</h3>
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. Or, there is a specific meaning to the word "force." At this level, calling a force a push or a pull is entirely appropriate. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. There are both living things and non-living objects in the concept of a force.

Answer:
HIV attacks a specific type of immune system cell in the body. It's known as the CD4 helper cell or T cell. When HIV destroys this cell, it becomes harder for the body to fight off other infections.
