Vo= 331+0.6T
360=331+0.6T
360-331=0.6T
29=0.6T
0.6T/29
T=6/290 so change it to simplest form and us formulas good luck
velocity = distance / time v= d/t firstly you change 3000 m into km distance D = 3000/1000 = 3 km secondly time t = 21 min using velocity formula v = d/t = 3 km/21min =0.142km/min
Answer: <span>D. A bimetallic strip bends so that the steel is on the outside curve
</span>
When something has an increased temperature, its volume will expand. Then, if the temperature drops, its volume should be smaller. From there option A and B are out since the liquid in thermometer is expand or move up.
When you put two kinds of different metal with a different coefficient of thermal expansion, the outer curve metal will be the one with lesser coefficient when temperature drop. Since the question about drop in temperature then the metal should be bend
Brass will expand 1.5 times more than the steel so the outer curve would be the steel.
<span>B) equal pressures are applied from your foot to the pedal to the brake pads.
That would be the answer.
Hope this helps!</span>
Protons are usually regarded by their mass, as mass is not specific to any gravitational acceleration. However, if you wished to find the weight of a proton on Earth, it would be:
Force (weight) = mass of proton * acceleration due to Earth's gravity
F = ma
F = (1.62 x 10^-27)(-9.8)
F = 1.5876 * 10^-26N
