Answer:
0.0055 seconds
Explanation:
To answer this question you need to know the equivalence:
1 second (s) = 5.5 (miliseconds) (ms)
Then you use the conversion factor:
-Put the value given and the units:
- Put in the denominator the equivalence with the same units:
- Put in the numerator the unit at which you want to convert the value given:
- Then multiply and divide the quantities:
Note that the same units in numerator and denominator are cancelled.
Answer:
8. We see water droplets on the outer surface of a glass containing ice cold water because condensation is happening! This happens when warm water vapour from the surroundings come into contact with a cool surface (in this case the cool glass) and loses heat and condenses, forming water droplets on the surface of the glass.
9 a) -248.15 celcius
b) 99.85 celcius
10. by using 2 syringes, one filled with water and one filled with air. when you compress it, you will find that the one with water barely compresses and the one filled with air should be able to be compressed quite a bit. and to the extent that the syringe is unable to be pushed down further, that is the maximum compressibility of air.
Answer: The mass of silver is 1.19 X 10^14 M g
Explanation: The volume of the truck is 402 cubic feet or 1.138 x 10⁷ mm.
The density of silver is 10.49 g/mL.
We need to find the mass of silver that will fit in this moving truck. Density equals mass divided by volume. So,
<h2>
d= m/v where m= mass m= d x V</h2><h2>
M=10.49 g/mL X 1.138 X 10∧7 mL</h2>
M=119376200 g 1 gram=10⁻⁶ Megagram 119376200= 1.19 X 10^14 Mg hence the mass of silver is 1.19 X 10^14 M g hopefully this will help you please mark me as brainlist
If the force is applied to lift the box, then there is no work done as the displacement of the box is not in the same direction of the box.
However, if the force is being applied to move the box in the direction of the force, then the work done is:
Work = force x distance
Work = 1500 x 3
Work = 4,500 Joules
