Answer:
In order to maximize 
, the cow must stand 3.74 ft away from the billboard, approximately.
Explanation:
The vertical angle subtended by the billboard at the cow's eye can be calculated from
Now, maximaxing , we have
Solving the equation for 
Which can be interpretated as the cow standing either one or the other side from the billboard. The next plot confirms that 's positive root, gives a maximum for the angle .
Answer:
1.29 moles
0.753 moles
0.745 moles
Explanation:
PV=nRT
n=PV/RT
n=(1)(34.2)/(0.0821)(323.7)
n=1.29
n=PV/RT
n=(1)(22.4)=(0.0821)(362.15)
n=0.753
n=PV/RT
n=(1)(16.7)/(0.0821)(273.15)
n=0.745
In the ideal gas equation, T is measured in Kelvin.
Answer:
Explanation:
Yes she is doing work. With or without the groceries, she is still doing work. She does more work with the groceries than without because Work is defined by F which is defined by mass. The mass increases with the groceries.
The work done is against the force of gravity.
Translational motion is a type of motion in which objects move with a change in position. The situation that best shows the translational motion is leaf blowing in the field.
Translational Motion:
It is a type of motion in which objects move with a change in position.
For example- leaf blowing in the field.
- Coin spinning on the desk does not change its position.
- A car in the parking lot with running engine does not change its position.
- Standing in feet is not any kind of movement.
Therefore, the situation that best shows the translational motion is leaf blowing in the field.

Answer:
f = 347.08 N
Explanation:
The frictional force exerted by the floor on the refrigerator is given as follows:
where,
f = frictional force = ?
μ = coefficient of static friction = 0.58
W = Weight of refrigerator = mg
m = mass of refrigerator = 61 kg
g = acceleration due to gravity = 9.81 m/s²
Therefore,
<u>f = 347.08 N</u>
