How is energy measured?​

Physics

Because a Btu is so small, energy is usually measured in millions of Btus. 1 Btu = the amount of energy required to increase the temperature of one pound of water (which is equivalent to one pint) by one degree Fahrenheit. This is roughly the heat produced from burning one match.

You are playing a game called "Will It Float?" In this game, you are given a large, square can of tuna. If you know the density
Delicious77 [7]
The only information you would need to decide if the can will float is the density of the can, which requires knowing the mass and volume. If the density of the can is less than one, the can will float. if it is greater than one, it will not float, as water's density is one.

5) A parallel series electric blasting circuit consists of 6 branches of 8 caps each. Cap legwire length is 28 ft. The cap circu
andrezito [222]

Answer:

Minimum DC current = 9 Ampere

Voltage = 74.862 V

Explanation:

Here in this questions three resistors are used in series

Resistance of cap circuit

R_1 =\frac{ 8* 2.3}{6} \\R_1 = 3.067

Here 2.3 is the resistance per cap

Resistance of bus wire

R_2 = \frac{50 * 4.02 }{1000} \\R_2 = 0.201

Where 4.02 is the resistance per 1000 feet of bus wire of gauge 16

Resistance of firing line

R_3 = \frac{(2*1000)* 2.525}{1000} \\R_3 = 5.05

where 2.525 is the resistance per 1000 feet of bus wire of gauge 14

Total resistance is equal to

R = R_1 + R_2 + R_3\\R = 3.067 + 0.201 + 5.05 \\R = 8.318

Current in firing line is equal to

1.5 * 6\\= 9

Voltage is equal to product of resistance and current

= 9 * 8.318\\= 74.862

Fantom [35]
The answer is C. Any physical property can be observed without changing the identity of the substance. That’s one of the main things that separates a physical and chemical property.
