The current in a hair dryer measures 11 amps. The resistance of the hair dryer is 12 ohms. What is the voltage?
Valentin [98]

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

Which statements describe the energy in a food web? Check all that apply. When an organism eats another organism, it loses energ
Neko [114]

Answer:  Producers have the greatest amount of available energy.

When an organism eats another organism, it gains energy.

Explanation:

A food chain is a linear sequence of transfer of food and energy when one organism is eaten by the other organism. A food web is the interconnection of two or more food chains. This happens when one organism belong to one food chain also consume organisms of same food chain or other food chain. A food chain includes trophic levels on the basis of the mode of feeding of the living beings.

Among the options given, Producers have the greatest amount of available energy. and

When an organism eats another organism, it gains energy. are correct.

Producers are the organism which are capable of producing their food either through photosynthesis or chemosynthesis. They are present at the base level of the food chain. They consist of large amount of energy as compared to all the trophic levels in the food chain.

When one organism eats other organism it gains energy because of the assimilation and digestion of the organism as food.

In Case 1, a mass M hangs from a vertical spring having spring constant k and is at rest in its equilibrium position. In Case 2
evablogger [386]

Answer: hello your question is incomplete attached below is the complete question

answer :  1/2 KD^2  ( option A )

Explanation:

P.E ( potential energy ) = mgd

In case 1 P.E = 0   i.e. mgd = 0  

Given that in case 2 the Mass M had moved through the Distance D by the compression of the spring

<u>The potential energy of the M in case 2 </u>

= P.E of M at rest + P.E of the spring

= 0 + 1/2 KD^2

If a satellite moves with constant speed in a perfectly circular orbit around the earth, what is the direction of the accelerati
9966 [12]
Traveling at any point on a curve, the force and the acceleration are toward
the center of the circle that the curve is part of.  On a perfectly circular path,
the force and acceleration are always toward the center of the circle.

If an object is tossed up into the air, what is its velocity at the top of the object's path? (Units are ms-1)
Novay_Z [31]

Answer: 0\ ms^{-1}

Explanation:

Given

If an object reaches the topmost point i.e. it cannot travel beyond that point as its velocity is zero at the topmost point

As some velocity is needed to move the object, so velocity at topmost point is zero
