Determine whether each substance will sink or float in corn syrup, which has a density of 1.36 g/cm3. Write “sink” or “float” in
2 answers:
Explanation:
- A substance will floats if it is having lower density than the density of the liquid in which it is placed.
- A substance will sink if it is having density greater than the density of the liquid in which it is kept.
Density of corn syrup =
1) Density of gasoline =
Density of the gasoline is less than the the density of corn syrup which means it will float in corn syrup.
2) Density of water =
Density of the water is less than the the density of corn syrup which means it will float in corn syrup.
3) Density of honey =
Density of the gasoline is more than the the density of corn syrup which means it will sink in corn syrup.
4) Density of titanium =
Density of the titanium is more than the the density of corn syrup which means it will sink in corn syrup.

<h2>Answer: 469 feet</h2>
Explanation:
This problem is a good example of Vertical motion, where the main equation for this situation is:
(1)
Where:
is the height of the stone at 6s (the value we want to find)
is the initial height of the stone
is the initial velocity of the stone
is the time at which we need to find the height
is the acceleration due to gravity
Having this clear, let's find from (1):
(2)
Finally:
This is the height of the stone at t=6s
Explanation:
Given that,
Voltage of household line, V = 110 V
Power of the hairdryer, P = 1650 W
During use, the current is about 1.95 cm from the user's hand.
(a) Power is given by :
(b) Again the power is given by :
R is resistance of the dryer
(c) The magnetic field produced by the dryer at the user's hand is given by :
Hence, this is the required solution.
