Explanation:
Plane mirrors always form virtual images meaning although the object appears to be in the other side of the mirror the light rays actually originate in front of it. The image is inverted meaning that when you lift your right hand it shows your left hand rising. and with true orientation.
Answer:
u need to make sure that comparison is = to shapes and then find the shapes sizes and add them
Answer:
False. the system does not complete the circle movement
Explanation:
For this exercise, we must find the rope tension at the highest point of the path,
-T - W = m a
The acceleration is centripetal
a = v² / R
T = ma - mg
T = m (v² / R - g)
The minimum tension that the rope can have is zero (T = 0)
v² / R - g = 0
v = √ g R
Let's find out what this minimum speed is
v = √ 9.8 1
v = 3.13 m / s
We see that the speed of the body is less than this, so the system does not complete the movement.
Answer: Thus the balloon will expand to 12.5 L if it suddenly rose to the surface.
Explanation:
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
Thus the balloon will expand to 12.5 L if it suddenly rose to the surface.
