I believe it is D because the more weight the more total speed it will end with
Answer:
a. 900 J
b. 0.383
Explanation:
According to the question, the given data is as follows
Horizontal force = 150 N
Packing crate = 40.0 kg
Distance = 6.00 m
Based on the above information
a. The work done by the 150-N force is
= 900 J
b. Now the coefficient of kinetic friction between the crate and surface is
= .383
We simply applied the above formulas so that each one part could calculate
To answer your question, no,
temperature does not always increase as it is heated. Adding heat does not always increase the temp.
For example, when water is boiling, adding heat does not increase the temperature. This occurs at the boiling temp of every substance that can vaporize.
Hope this explanation was helpful and brief! :)
Given:
450 grams of water (Tw = 24 C)
Thermal capacity of the beaker = negligible
Q = 0
Tice = 0 C
Tfinal = 8 C
450g * (Tf - Tw) + m_ice * (Tice - Tw) = 0
450g * (8 - 24) + m_ice (0 - 24) = 0
solve for m_ice
Answer:
Explanation:
Angular velocity ω = 2π / T = 2 x 3 . 14 / (4 x 60 ) = .026 rad / s.
d = D Sin ( ωt + θ ) where D = amplitude = 11 m θ = initial phase.
-11 = 11 sin ( 0 + θ ) = sin θ = -1 , θ = - π /2
So, d = D Sin ( ωt - θ )
d = 11 Sin ( .026 t - π /2 ) is the required equation.
