Answer:
(1) 10⁻⁴m = 0.0001m = 0.1mm
Explanation:
To be able to solve let's analyze each of the possible answers, let's start with:
(2) 10⁻²m = 0.01m = 1cm
This is not possible since a sheet cannot have one centimeter of thickness.
(3) 10°m = 1m We must remember that any number raised to zero is equal to 1
This is not possible since a sheet cannot have one meter of thickness.
(4) 10²m = 100m
This is not possible since a sheet cannot have one hundred meters of thickness.
(1) 10⁻⁴m = 0.0001m = 0.1mm
This is the answer, since a sheet of paper can be less than a millimeter thick.

If a car accelerates from rest at a constant 3.0 m/s/s(3.0m/s^2) A. how long will be required to each 15 m/s B. What distance does the car travel in the 15 minutes?
Answers
Answer: a. 5 seconds
b. 810,000 meters
Explanation:
Part a:
Listing everything is gives you:
Vi = 0
a = 3
Vf = 15
t = ?
Choose a kinematic equation to find the missing variable
I choose this one: Vf = Vi + at
15 = 0 + 3t
solving for t gives you t = 5seconds
Part b:
Listing everything it gives you:
t = 15min = 900seconds
a = 3
vi = 0
Δx = ?
Choose a kinematic equation
I did this one: Δx = Vit+[tex]\frac{1}{2} at^2[/tex]
Δx = (0)(900) + [tex]\frac{1}{2} (3)(900)^2[/tex]
you end up with Δx = 810,000m

Why does the skateboarder continue to move forward when he hits the
trash? What is the external force?
Answers
Answer:
According to Newton's first law: An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
There is a force that moves the skater and his skate forward, after the hit, his speed is reduced, but this force is not completely counteracted, and that's why he continues moving forward.
What are the horizontal and vertical components of a lizard’s displacement if it has climbed 7m directly up a tree?
Answers
Answer:
The horizontal component is zero.
The vertical component is [tex]7\sin\theta[/tex]
Explanation:
Given that,
The lizard climb 7m directly up on a tree.
We know that,
The horizontal component is
[tex]x=\cos\theta[/tex]
The vertical component is
[tex]y=\sin\theta[/tex]
If the lizard climb 7m directly up on a tree then,
We need to find the components
Using given data
The horizontal component of lizard is
[tex]x=0[/tex]
The vertical component is
[tex]y=7\sin\theta[/tex]
Hence, The horizontal component is zero.
The vertical component is [tex]7\sin\theta[/tex]

When area increases, pressure decreases. Find two situations where this principle is applied.

Pressure can be defined as the force per unit area hence there is an inverse relationship between pressure exerted by a substance and the area of that substance. For instance,
(1) if a bag of sand if filled with sand and an individual steps on this bag. The feet of he individual will form no shape/displace little sand sideways in the bag. But if the same quantity of sand is poured in a bigger bag (larger area) and the same individual stands on the bag, the feet of the individual will "sink" (decreased pressure from the bag) displacing some sand sideways.
(2) The straps of a bag are made wide (and not slim) so that the bag can exert lesser pressure on the shoulders when the same quantity of load is carried by the bag than if the straps were made narrow/slim.

In order to do this he asked to speak in private with the king, saying that he had a most important communication to make.
"What is it?" asked the king.
"Sire," answered the grand-vizir, "it is most dangerous for a monarch to confide in a man whose faithfulness is not proved. You do not know that this physician is not a traitor come here to assassinate you."

A disc is rotating with angular speed 50rad/sec having radius r=2m. Find angular velocity of point A wrt C, O and B.
Don't spam!
Answers
Answer:
50 rad/s
Explanation:
Angular velocity equals the relative linear velocity divided by the radius.
vb = va + ωr
ω = (vb − va) / r
The disc has angular velocity 50 rad/s and radius 2 m. So the linear velocity of point A is v = (50 rad/s) (2 m) = 100 m/s. The linear velocity of point C is v = (50 rad/s) (1 m) = 50 m/s. And the linear velocity of point B is -100 m/s.
The angular velocity of point A with respect to point C is:
ω = (100 m/s − 50 m/s) / (1 m)
ω = 50 rad/s
The angular velocity of point A with respect to point O is:
ω = (100 m/s − 0 m/s) / (2 m)
ω = 50 rad/s
The angular velocity of point A with respect to point B is:
ω = (100 m/s − -100 m/s) / (4 m)
ω = 50 rad/s
