Answer:
c = e > b = d > a
Explanation:
Given vectors are all unit vectors, therefore they have a magnitude of 1
<h3>Let a, b be two vectors and magnitude of cross product of these two vectors is (magnitude of a) × (magnitude of b) × (sine of angle between these two vectors)</h3>
As all are unit vectors their magnitude is 1 and therefore in this case the cross product between any two vectors depends on the sine of angle between those two vectors
In option a as both the vectors are same, the angle between them will be zero and sin0° will also be 0
In option b angle between those two vectors is 135° and sin135° is 1 ÷ √2
In option c angle between those two vectors is 90° and sin90° is 1
In option d angle between those two vectors is 45° and sin45° is 1 ÷ √2
In option e angle between those two vectors is 90° and sin90° is 1
So by comparison of magnitudes of cross products in each option, the order will be c = e > b = d > a
Answer:
E) e
Explanation:
Impulse is equal to the product between the force applied (F) and the time interval of the collision (
):
This means that we can calculate the force for each collision dividing the impulse by the time interval:
Let's apply the formula to each case:
A) 
B) 
C) 
D) 
E) 
Therefore, the force is the maximum for collision E).
Answer: I think its called the "photosphere"
Explanation: Its very unsafe to look at but when you look up at the sun, visible lights radiates the sun so we can see it. Hope this helps!

Answer:
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work.
