The answer is actually True, I just took the test and it was correct.
Answer:
The value we are given in the question is 1.24 * 10^7. This form of writing number is called scientific notation. The standard notation is the normal, regular way of writing numbers. Scientific notation and standard notations are interchangeable.
1.24 * 10^7 written in standard notation will be = 1.24 * 10000000 = 12400000.
Thus, the mass of the meteoroid was 12400000 kg.
Explanation:
Answer:
8892 ml = 8892 gm = 8892000 mg
1 ml = 1 gram
8892 ml = 8892 gram
1 gram or ml = 1000 milligram
8892 ml = 8892 × 1000 = 8892000 milligram
hope this helps
have a good day :)
Explanation:
remember: 1 kilogram = 1000 gram = 1000000 milligram.
Milliliter is expressed same as gram and liter is expressed same as kilogram.
1 meter = 100 cm, 1 kilometer = 1000 meter,
1 cm = 10 millimeter.
Let's see: frequency of cellular phone waves (GSM phones) is (800-1900 MHz). If we look at the table of the electromagnetic spectrum, we can see that this range is contained within the frequencies of the microwaves, which include waves in the range 300 MHz-300 GHz.
So, summarizing, the correct answer is "microwaves".
Answer:
Explanation:
Since the roundabout is rotating with uniform velocity ,
input power = frictional power
frictional power = 2.5 kW
frictional torque x angular velocity = 2.5 kW
frictional torque x .47 = 2.5 kW
frictional torque = 2.5 / .47 kN .m
= 5.32 kN . m
= 5 kN.m
b )
When power is switched off , it will decelerate because of frictional torque .
