Answer:
Explanation:
The more aerodynamic a vehicle is the less wind resistance there is meaning there is better gas mileage because it dont have to push so hard against wind and it also helps with the eye appeal
Answer:
It is directed inward, toward the center of a circle.
Answer:
B) T > ma.
Explanation:
To solve this problem, we have to analyze the forces acting in the horizontal direction.
In the horizontal direction, we have:
- The horizontal component of the tension in the wire, , where T is the magnitude of the tension and the angle that the wire makes with the horizontal
Since this is the only force acting on the box in the horizontal direction, this is also the net force, so it is equal to the product of mass and acceleration (Newton's second law of motion):
where
m is the mass of the box
a is the acceleration
We can rewrite the equation as
The angle in this problem is , so
Therefore, the correct option is
B) T > ma.
Answer:
The speed of planes is 419.31 miles per hours
Explanation:
Given that
S= 10 miles
And we have to find .
From triangle ABC
by differentiating with respect to time t
Now when S=10 miles then
x= 9.53 miles
So
So the speed of planes is 419.31 miles per hours
By comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.
<h3>What is melting point?</h3>
The melting point is the point at which the solid would change to liquid. The boiling point is the point at which a liquid would change to gas. Now we know that the melting and the boiling point of a signature of a compound and can be used to identify a pure substance.
Hence, by comparing the melting and the boiling points of the test substance to that of the substances that are recorded in the literature, we can be able to obtain the identity of a substance.
