Answer:
1.93 cm
Explanation:
The Image Equation for the first lens will be
1/f1 = 1/do - 1/d1
Where f1 = 17cm and d1 = 28.3cm
1/do = 1/f1 + 1/d1
= 1/17 + 1/ 28.3
do = 10.62cm
This image (which is real, inverted, and enlarged) becomes the object for the second lens as we again apply the Image Equation for the second lens
1/ f2 = 1/d2 + 1/d
Since the lenses are 12.8 cm apart, the image formed 10.62 cm to the left of lens #1 is located 2.18 cm to the right of lens #2 so the object distance, then, is
1/d2 = 1/f + 1/d
= 1/17 + 1/2.18
d2 = 1.93cm
If the temperature is increased the particles gain more kinetic energy or vibrate faster. This means that they move faster and take more space.
Answer:
Explanation:
When the hot copper and the liquid water reaches equilibrium, they have the same temperature; when this happens, the amount of heat released by the copper is equal to the amount of heat absorbed by the water:
where
is the mass of the copper
C_c=0.385 J/g˚C is the specific heat of copper
T_f=50˚C is the final temperature of both substances
is the mass of the water
C_w=4.184 J/g˚C is the specific heat of the water
T_c is the initial temperature of the copper
T_w=20˚C is the initial temperature of the water (room temperature)
Solving for T_c, we find:

t=(0-(250sin75)^2)/-9.8
<span>the distance one is (2500+610)- (250m/s*cos75)*t=Dh Dh=horizontal distance </span>
<span>the max height one is d=0.5*9.8*t^2 </span>
<span>d= max height subtract 1800-d</span>
Answer: It goes inside filling most of it .
Explanation: This happens because the bottle is empty and the bucket is full of water.
