Answer:
m = 20,000 kg
Explanation:
Force, 
Acceleration of the shark, 
It is required to find the mass of the shark. Let m is the mass. Using second law of motion to find it as follows :
F = ma
Putting the value of F and a to find m
So, the shark's mass is 20,000 kg.
Answer:
1%
Explanation:
Percent error can be found by dividing the absolute error (difference between measure and actual value) by the actual value, then multiplying by 100.
The measured value is 2.02 meters and the actual value is 2.00 meters.
First, evaluate the fraction. Subtract 2.00 from 2.02
Next, divide 0.02 by 2.00
Finally, multiply 0.01 and 100.
The percent error is 1%.

Answer:
Magnetic substances: steel tank, iron ball, nickel hinge
Non magnetic substances: wooden table, glass marbles, silver medal.
Explanation:
The substances which experience a force of attraction when placed in a magnetic field are called magnetic substances. For example, iron, cobalt and nickel.
The substances which do not experiences a force of attraction when placed in a magnetic field are called non magnetic substances. For example, wood, rubber, glass, etc.
Answer:
The intensity of the light after passing through the two polarizing filters is 4.00 units
Explanation:
Io = 25 + A
= 25 + 9
= 34
Intensity of light through first polarizer,
I1 = Io/2
= 34/2
= 17 units
angle between axis of frist and second polarizers, theta = 55 + 6
= 61 degrees
Intensity of light passing through second polarizer,
I2 = I1*cos^2(theta)
= 17*cos^2(61)
= 4.00 units
