Answer:
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.

Answer:
C. strike-slip fault
Explanation:
The scientist must have observed a strike- slip fault.
A fault is an evidence of brittle deformation of the crust in the presence of applied stress on earth materials. Here, the earth material is the rock subjected to tension.
Where a fault occurs, there must have been movement between two blocks of rocks. The direction of movement helps us to delineate the fault type.
- When two blocks moves past each other horizontally, it is a strike-slip fault like rubbing your palms together.
- When a block moves in the direction of the dip, it forms a dip-slip fault which results in a fault-block mountain characterized by graben and horst systems.
Option A, Plateau is a table landform usually a mountain with flat peak.
Option B is a bowl shaped stratigraphic pattern in which the youngest sequence is at the core of the strata or a fold.
So, the most fitting option is C, a strike-slip fault.
Answer:
a)
b)
Explanation:
Given that
Initial velocity u =0 m/s
Speed at 5 s v= 282 m/s
Rocket accelerated up to 5 s :
We know that
v= u + at
282= 0+ a x 5
So the acceleration
Rocket come to rest in 1.4 s :
Final velocity of rocket v=0 m/s
Initial velocity = 282 m/s
v= u + at
0= 282 - a x 1.4
So the deceleration
Answer:
- Fundamental quantities are quantity whose definition does not depend on other quantities.
There are seven fundamental quantities in physics:
Length (measured in metres)
Mass (in kilograms)
Time (in seconds)
Electric current (in Ampere)
Temperature (in Kelvin)
Amount of substance (in moles)
Luminous intensity (in candela)
- On the other hand, derived quantities are quantities that are defined using the fundamental quantities.
For example, derived quantities are:
Velocity, which is the ratio between length and time
Acceleration, which is the ratio between velocity and time
Energy, which is a product of mass and velocity squared
And many others.
