Average velocity = Total Displacement / Total time taken
Total displacement is the distance from starting to end point.
35km west then 90km north. When you will draw this and connect starting to end point. You will get a right angled triangle.
So displacement =
= 96.56 km
So, Total displacement = 96.56 km
So, Average Velocity = 96.56 / 2 = 48.28 km/hr
Answer:
D. Synthetic polymers are inexpensive to produce.
Explanation:
Hailey should include that synthetic polymers are inexpensive to produce as a benefit of synthetic polymers.
Synthetic polymers are artificially produced. These polymers come about from petroleum oil. Their hydrocarbons are industrially worked to produce the long chain hydrocarbons to form polymers.
Most of these polymers are very cheap to produce and does not cost too much. This is why they almost found everywhere.
Explanation:
Answer:
Electric field, 
Explanation:
It is given that, a proton in a particular electric field experiences an electric force whose magnitude is equal to the weight of the proton such that,
or
So, the magnitude of electric field at the location of the proton is 
. Hence, this is the required solution.
Answer:
Absorbed and reflected
Explanation:
B is reflected because you can’t see the red arrow which represents a light that bounces off of it and a aired up sword because you can see it win through the object shown in the picture
Answer:
0.208 N
Explanation:
Parameters given:
Current, I = 2A
Angle, A = 60°
Magnetic field strength, B = 0.2 T
Length, L = 0.6 m
Magnetic force is given as:
F = I * L * B * sinA
F = 2 * 0.6 * 0.2 * sin60
F = 0.24 * sin60.
F = 0.208 N
