Answer: Acceleration is a measure of how fast velocity changes. Acceleration is the change of velocity divided by the change of time. Acceleration is a vector, and therefore includes both a size and a direction. In short, acceleration is the rate at which speed changes.
Answer:
a=2.304×10¹⁶m/s²
Explanation:
Given data
Distance d=2.5 nm=2,5×10⁻⁹m
Mass of proton m=1.6×10⁻²⁷kg
charge of proton q=1.6×10⁻¹⁹C
To find
acceleration a
Solution
Apply the Coulombs Law
Where k is coulombs constant (k=9×10⁹Nm²/C²)
q=q₁=q₂
r=d
So
Answer:
substances will move faster and become warm to the touch.
Explanation:
when the radiation from the sun comes down and hits substances, the substances absorbs the radiation making them warm. the absorbed energy is transformed into heat energy. this heat energy plays an important role in regulating the temperature of the Earths crust, surface waters, and low atmosphere.
Voltage is given by the formula
V = IR (Ohms law)
where V is the Voltage
I is the current
and R is the Resistance
Here it is given that the current is I=11
Resistance is R =12
so plugging this in the formula
V = IR
V= 11 * 12
V= 132 Volts
So the Voltage for the given dryer is 132 Volts
1 is b because a runs 20 and b rus 102 is c
