Answer:
Option B. They use thermal updrafts to stay aloft
Explanation:
The sunlight warms the surface of the earth during noon and morning time and when this warming of the Earth's surface is not evenly done or uniform then this gives rise to the thermals. These are the rising air columns and rises when the air nearest to the earth heats up.
This is how some birds like vultures make use of the thermal updrafts to maintain flight.
Answer:
An object which moves in the negative direction has a negative velocity. If the object is speeding up then its acceleration vector is directed in the same direction as its motion (in this case, a negative acceleration).
Explanation:
<span>d) more information is needed in order to figure this out..... I would say because how large someone is would not change the direction of them while skating.</span>
<em><u>D. acceleration Hope this helps!</u></em>
Answer:
Explanation:
Given that :
The current I = 8.6 A
The length vector L = 2.3 m i
The force vector is = -2.0 j N
When L = 2.3 m i ; the
Force vector F = (2.0 i - 4.8 k) N
Compute the components of the magnetic field as follows:
Replacing 8.6 A for I ; -2.0 j N for F & 2.3 m i for L
However in y direction ; we have :
Hence, the component of magnetic field is as follows:
