Answer: false
Explanation:
While kilograms are the unit used to measure body mass, the device used is a scale.
Hope it helps :)
Weight on any planet is (mass) x (acceleration of gravity there).
Acceleration of gravity on Earth is about 9.8 meters per second² .
So weight of 50 kg on Earth is (50 x 9.8) = <u>490 newtons</u>.
(That's about 110.2 pounds.)
Science is open to change because scientists agree that there are no absolute truths, only the best explanations for the data
there are specifically two cases when science can change: -new data is discovered (for example new skeleton makes us revise the known history of homo species)
-a new model is proposed that fits the data better (such as the heliocentric model of Copernicus)
The energy that then radiates out from the surface, longwave radiation, is trapped by the same greenhouse gases, warming the air, oceans, and land. This process, appropriately dubbed “the greenhouse effect,” is how global warming occurs.
Answer:
T=9.4 N
Explanation:
We are given that
Mass of wire,m=16.5 g=
kg
1 kg=1000g
Length of wire,l=75 cm=
m
1 m=100 cm
Wavelength of transverse wave=
m
Frequency=
Mass per unit length=
Where
frequency of wave
=Wavelength of wave
Speed of wave=v
Using the formula
Using the formula
Hence, the tension,T=9.4 N
