This is reactivity. It describes how easily one substance reacts with another
Answer:
0.2 m/s^2
Explanation:
initial speed 14m/s
final speed 20m/s
acceleration:
(20m/s - 14m /s) /30s = (6m/s)/30s = 0.2 m/s^2
The mass of the water with the sugar dissolved in it is 55 grams. This is because when you add the weight of the water, and the sugar that you added, it is 55.
Answer:
The total charge Q of the sphere is .
Explanation:
Given that,
Radius = 5 cm
Charge density
We need to calculate the total charge Q of the sphere
Using formula of charge
Where, = charge density
V = volume
Put the value into the formula
Put the value into the formula
Hence, The total charge Q of the sphere is .
Answer:
D. none of them.
Explanation:
This is because Ohm's law is:
Voltage = Current × Resistance
or,
V = IR
