Answer:
Explanation:
Newton's law of cooling
Rate of cooling
Where To is the surrounding temperature
T is object temperature at any time t
now by removing proportionality sign
Now by separating variables
So
Where C is constant
C' is also a constant and it can be find by using boundary conditions.
Answer:
Explanation:
An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. When assuming its usual position (i.e., when not drawn), there is no energy stored in the bow. Yet when its position is altered from its usual equilibrium position, the bow is able to store energy by virtue of its position. This stored energy of position is referred to as potential energy. Potential energy is the stored energy of position possessed by an object.
The angle is found by taking the arctangent of the vertical angle divided by the horizontal angle
θ = arctan(18/25) = 35.75°
36° is the closest answer.
Answer:
534 j
Explanation:
100 lbs = 45.359 kg
work = F * d
= 45.359 * 9.81 * 1.2 = ~ 534 j
Answer: Sound waves will not be transformed into electrical signals.
Explanation: Just took the test and got a 100!
