Answer:
20 N
Explanation:
the force of static friction maximum = Fn * .15 = 200 * .15 = 30 N
the force of friction will cancel out the 20 N force applied
Ff = 20 N
Answer:
Explanation:
500 W = 500 J/s
500 J/s(2 min(60 s/min) = 60000 J
Answer:
1.52 * 10⁵ K
Explanation:
When the temperature of a blackbody radiator increases, the overall radiated energy increases and the peak of the radiation curve moves to shorter wavelengths. When the maximum is evaluated from the Planck radiation formula, the product of the peak wavelength and the temperature is found to be a constant.
By Wien's Law,
λ * T = 2.898 * 10⁻³ mK
∴ T = 2.898 * 10⁻³/λ
Given λ = 19 nm = 19 * 10⁻⁹
T = 2.898 * 10⁻³ / 19 * 10⁻⁹
=1.52 * 10⁵ K
Answer:
Velocity is a function of time and defined by both a magnitude and a direction. [1] Often in physics problems, you will need to calculate the initial velocity (speed and direction) at which an object in question began to travel. There are multiple equations that can be used to determine initial velocity. Using the information given in a problem, you can determine the proper equation to use and easily answer your question.

Answer:
We usually travel in January or Feb for our tropical get-a-way. For those of you that have traveled in the fall and winter...
What is the real difference...Like in the floral and fauna, weather, and the capacity of the resorts between these 2 times of the year.
