Answer:110N
Explanation:
ma=f in/ f out (formula)
Input: 20.0N
Ma:5.5
Output:?
^ given information
Plug the numbers into the equation ~
5.5= 20N/?
5.5x20=110N
If a certain lever has a mechanical advantage of 5.5, then the leaver would be able to lift a load of 110 Newtons with an input force of 20.0 N
What is the mechanical advantage?Mechanical advantage is defined as a measure of the ratio of output force to input force in a system, It is used to analyze the forces in simple machines like levers and pulleys.
Mechanical advantage = output force(load) /input force (effort)
As given in the problem a certain lever has a mechanical advantage of 5.5, then we have to find out how heavy of a load could the lever lift with an input force of 20.0 N,
Mechanical advantage = output force(load) /input force (effort)
5.5 = load / 20.0 Newtons
load = 5.5 × 20
= 110 Newtons
Thus, the leaver would be able to lift a load of 110 Newtons with an input force of 20.0 N

A motor pushes a car with a force of 35 N for a distance of 350 m in 6 s.
a. How much work has the motor accomplished?
Answer:
2041.66666667
Explanation:
35 N → 350 METERS for 6 seconds
force distance
350 M / 6s = 58.3
58.3 x 35 N = 2041.66666667 work
What direct method of generating electricity?
For Me Is "Hydropower."
Because Hydropower is most efficient method of generating electricity because 95 per cent of the energy of flowing water gets converted into electricity—only five per cent of the energy is converted into other forms of energy.

A 2.60 kg block is in equilibrium on an incline
of 24.3◦
.
The acceleration of gravity is 9.81 m/s
2
.
What is Fn of the incline on the block?
Answer in units of N.
Answer:
W = m g = 2.60 * 9.81 = 25.5 N weight of block
Fn = W cos theta = 25.5 N * cos 24.3 = 23.2 N normal force of plane

How is electricity generated and transmitted to provide electricity to homes.
Answer:
Electricity generated at the power plant reaches our homes through multiple substations, transmission and distribution lines, and transformers. Newly generated electricity is transmitted at extremely high voltages ranging from 275,000 to 500,000 volts in order to reduce transmission losses.How long did it take for the dinosaurs to die after the asteroid?.

Calculate the acceleration of a truck moving along a straight path if its speed increases from
0.0 m/s to 15 m/s in 10.0 s.
Answer:
I'm not to sure but I think the answer is 1.5m/s^2
Explanation:
Acceleration = Change in Velocity over Time.
So we get 15 - 0.0 divided by 10.0 which = 1.5m/s^2
But again I'm no expert I'm learning this stuff just like you guys.

) The magnitude of scalar product of two unit vectors perpendicular to each other is
This question involves the concept of the scalar product.
The magnitude of the scalar product will be "0".
SCALAR PRODUCTThe scalar product, also known as the dot product of the two vectors is given by the following formula:
[tex]A.B = |A||B|Cos\theta[/tex]
where,
A.B = Scalar product = ?|A| = Mangnitude of vector A = 1 unit|B| = Magnitude of Vector B = 1 unitθ = Angle between vectors = 90°Therefore,
[tex]A.B = (1)(1)Cos90^o = (1)(1)(0)[/tex]

The diameter of earth is largest when measured around the.
Answer:
equator
Explanation:
The diameter of earth is largest when measured around the equator, due to the equatorial bulge.
The equatorial bulge is a phenomenon caused by the Earth's diameter being wider in the Equator.
A straight line with its endpoints located on the edge of the circle and its center is used to calculate the diameter of a circle. Latitudes like the equator and the Arctic Circle have diameters that can be calculated by scientists.
The Equator is the place on Earth where it is the broadest. At the equator, the circumference of the Earth is 40,075 km.
