Answer:

Power used by dryer is 2160 watts

Explanation:

It is given that,

Current used by clothes dryer, I = 9 amps

Voltage used by dryer, V = 240 volts

We have to find the power used by it. Mathematically, the relationship between voltage, current and power is given by :

$P=V\times I$

Putting the values of I and V in above equation as :

$P=240\ V\times 9\ A$

P = 2160 watts

Hence, the power used by dryer is 2160 watts.

If a cars velocity is slowing down is it considered a positive or negative acceleration?

Natali [406]

Answer:

Negative

Explanation:

Observe that the object below moves in the positive direction with a changing velocity. An object which moves in the positive direction has a positive velocity. If the object is slowing down then its acceleration vector is directed in the opposite direction as its motion (in this case, a negative acceleration).

Ali mixes 20g of Sodium Chloride in 100g of water at 15 Degree °C. Calculate the mass of the solution

Lera25 [3.4K]

Answer:

The mass of the solution is 120 g.

Explanation:

The mass of the solution is given by:

$m_{sol} = m_{1} + m_{2}$

Where:

$m_{sol}$ : is the mass of the solution

$m_{1}$ : is the mass of the solvent

$m_{2}$ : is the mass of the solute

In the solution, the solvent is the majority compound (in mass) and the solute is the minority (in mass), so the solvent is the water and the solute is sodium chloride.

Hence, the mass of the solution is:

$m_{sol} = m_{1} + m_{2} = 100 g + 20 g = 120 g$

How do stars serve as evidence for the expansion of the universe and the Big Bang theory?

castortr0y [4]

Answer:

The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.
