Hello!
Why should you wash the dishes when you are going to eat on them again eventually? People usually will clean up after whatever they’ve done to make it look good in the moment even though they might mess it up again.
Hope this helps!
Mechanical energy = potential energy + kinetic energy
The ball is on the ground so it has no potential energy. that's all i know.
Because the force of gravity attracts the comets towards the sun
HELLO JHUVI THE PROBLEM IS VERY EASY
FIRST,
F=5.8X10^2N & DISPLACEMENT (D)=8M
NOW, WORK=FORCE (F) X DISPLACEMENT (D)
SO WORK =5.8X10^2X8 = 4640 N/M
SO WE HAVE WORK WHICH IS 4640 N/M
SECOND,
POWER = WORK /TIME
SO, POWER = 4640/15 (T=15 MIN GIVEN IN QUESTION)
SO POWER = 309 WATT
THATS IT SIMPLE
The amount of gold in decigrams if 450 micrograms is needed is 4.5 × 10-³ decigrams.
<h3>How to convert micrograms to decigrams?</h3>
According to this question, 450 micrograms of a sample of gold is needed but we only have a mass balance that measures in decigrams.
This means that we are to convert the amount of gold you need to decigrams by comparing the exponents.
The conversion factor of micrograms to decigrams is as follows:
1 micrograms = 1 × 10-⁵ decigrams
This means 450 micrograms is equivalent to 450 × 1 × 10-⁵ = 4.5 × 10-³ decigrams
Therefore, the amount of gold in decigrams if 450 micrograms is needed is 4.5 × 10-³ decigrams.
