Answer:
Impulse-The effect of force acting over time to change the momentum of an object.
momentum-The product of mass of a particle and its velocity.
Answer:
220km
Explanation:
Given parameters:
Distance traveled from Minnehaha to Nut Plains = 11km
Distance traveled to Dover = 209km
Unknown:
The distance the soft drink distributor traveled = ?
Solution:
To solve this problem, we must understand that distance is the total length of path covered in a journey.
So;
Distance = 209km + 11km = 220km
The soft drink distributor covered 220km
Good conductors of electricity have larger conductivity values than insulators.
A material that obeys Ohm's law reasonably well is called an ohmic conductor or a linear conductor.
The resistance of a conductor is proportional to the conductivity of the material of which the conductor is composed.
Answer: Options 1, 2 and 4.
<u>Explanation:</u>
In physics and electrical engineering, a conductor is an article or kind of material that permits the progression of charge in at least one headings. Materials made of metal are basic electrical conduits.
Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. Most atoms hold on to their electrons tightly and are insulators.
Answer:
option 2 is correct
Explanation:
the angle between p*q and p+q is 90 degree which is equal to π/2
it is rule that product of two vectors is always perpendicular to the plane in which both the vector lie
Explanation:
Mass of the Earth is equal to,
Any number can be written in the form of scientific notation as :
m is the real number
n is any integer
Mass of the earth can be written in the form of scientific notation as :
Here,
m = 5.97
n = 24
Hence, this is the required solution.
