Answer:
meter, kilogram
Explanation:
Here we want to know how big the tiger is. This means that we want to measure its size and possibly its mass.
The size is actually a measure of the length of the tiger, and length is measured in meters.
The mass of an object, instead, is a measure of the "amount of matter" in the substance, and it is measured in kilograms.
The other options are wrong because:
- The second is the unit of time
- The candela is the unit of the luminous intensity
- The mole is the unit of the amount of substance, and it is used for gases
- The ampere is the unit of the current
Barium fluoride(BaF2) is a chemical compound of barium and fluorine and is a salt. It is a solid which can be a transparent crystal.
Density=mass÷volume
mass=density×volume
mass=2×8=16 g
Answer:
The formula for induced EMF is ε = BLv
The B is the magnetic field of the earth. I will solve this problem with a value of 1 X 10-4 T for the accepted value of the earths magnetic field. However, with that said, your book may use a different value. If that is the case, this answer will be wrong, but the formula works. All you will need to to is find the value for the earth's magnetic field that your book wants you to use, and substitute for 1 X 10-4 T.
ε = BLv
ε = (1 X 10-4)(1.8 X 104)(7.8 X 103) = 14040 V
Again, if your book does not like this answer, use this equation
ε = (B)(1.8 X 104)(7.8 X 103) and just plug in a different value for B found in your text
