A zinc block with a mass of 230 g is given 1320 J of energy. What is the change in
Mariana [72]

Answer:

14.7°C

Explanation:

Q = m·ΔT·c

ΔT = \frac{Q}{m*c}

ΔT =\frac{1320 J}{230 g* 0.39 J/gC}

     = 1320 J / ((230 g) * (.39 J/g°C)

ΔT = 14.7 °C

What are two methods to solve the energy crisis?​
grin007 [14]

Possible Solutions to the Problem of Global Energy Crisis
Move Towards Renewable Resources. ...
Buy Energy-Efficient Products. ...
Lighting Controls. ...
Easier Grid Access. ...
Energy Simulation. ...
Perform Energy Audit. ...
Common Stand on Climate Change. We've got to reduce our dependence on foreign oil; it's a matter of homeland security. Fine. Nobody's arguing. But the solutions that get offered -- drilling in ANWR, mandating better automobile fuel efficiency, pushing ethanol -- don't really solve anything. They're politically impossible, or too expensive, or contrary to free-market forces. They're losers.
Energy-independence advocate Gal Luft looks for winners. The former lieutenant colonel in the Israel Defense Forces and counterterrorism expert fervently believes that the only way to make America safe is to make it energy independent. And so as executive director of the Institute for the Analysis of Global Security and cofounder of the Set America Free Coalition, he has set out to do just that.

Luft advises Congress and security companies. He briefs industrial and environmental groups. Yet what separates him from other energy specialists are his pragmatic solutions. He doesn't peddle pie-in-the-sky political strategies. He's a realist. He has a single goal: freeing America from the grip of foreign oil. And he wants to do it now. At right are four steps he says we can -- and should -- take today.

Diamonds are measured in carats, and 1 carat=0.200g. The density of diamond is 3.51g/cm^3. What is the volume of a 5.0-carat dia
const2013 [10]
Convert the amount of substance in carat to grams.
                 (5.0 carat) x (0.200 g / 1 carat) = 1 g
The volume of the substance is obtained by dividing the mass by the density,
                             v = m / d
                             v = 1 g / (3.51 g/cm³) = 0.2849 cm³
Therefore, the volume of a 5.0 carat diamond is approximately 0.285 cm³.
