Answer:
Heat is similar to and different from internal energy
Explanation:
Similarity:
First thing to remember is that heat and internal energy are both different forms of energy. Secondly, heat is directly proportional to internal energy. When you provide heat to the system, its internal energy will increase. So, heat is the part of internal energy.
Difference:
Internal energy is the summation of kinetic and potential energy of a system, means it depends upon movement of particles as well as the particular position of the system while heat is the transfer of the energy due to difference of degree of hotness and coldness of body or a system.
<span>Gvn that,
Radius r = 1.65cm
then the Diameter d = 3.3 cm
Volume V = 4/3pi*(D/3)^3
= 4/3*3.14*(3.3)^3/8
= 4/3*3.14*35.937/8
= 4/3*3.14*4.492125
= 4/3*14.1052725
= 56.421.9/3
= 18.80703 dm^3
We know that gravity g=9.806m/s^2
p pt = 2.14 * 104 kg/m^3 = 21.4
p hg = 1.36 * 104 kg/m^3 = 13.6
Real Weight Wr = V*p pt*g
= 18.80703*21.4*9.806
= 3946.625 N
Buoyant force Fb= V*p hg*g
= 18.80703*13.6*9.806
= 2508.136 N
Apparent weight = Wr-Fb
= 3946.625-2508.136
= 1438.489 N
Therefore Apparent weight is 1438.489 N</span>
Answer:
<em>The chef can make 8 casseroles</em>
Explanation:
<u>Units Conversion</u>
We need to recall 1 gallon = 16 US cups.
A casserole needs 1 cup of milk, and the chef has 0.5 gallons of milk. Those 0.5 gallons are equivalent to 0.5*16 = 8 cups, thus the chef can make 8 casseroles.
Gwen's position is a function of his velocity and time
Gwen's position at 45 seconds is 63.9 feet
<h3>How to determine Gwen's position at 45 seconds?</h3>
The function is given as:
v(t) = 250sin(t^2/120)/(t + 6)
When t = 45, we have:
v(45) = 250sin(45^2/120)/(45 + 6)
Evaluate the sum, the exponent and the quotient
v(45) = 250sin(16.875)/(51)
Evaluate the sine ratio
v(45) = 250 * 0.2903/51
Evaluate the product and quotient
v(45) = 1.42
The position is then calculated as:
S(45) = v(45) * 45
This gives
S(45) = 1.42 * 45
Evaluate the product
S(45) = 63.9
Hence, Gwen's position at 45 seconds is 63.9 feet
