When the object is at the focal point the angular magnification is 2.94.
Angular magnification:
The ratio of the angle subtended at the eye by the image formed by an optical instrument to that subtended at the eye by the object when not viewed through the instrument.
Here we have to find the angular magnification when the object is at the focal point.
Focal length = 6.00 cm
Formula to calculate angular magnification:
Angular magnification = 25/f
= 25/ 8.5
= 2.94
Therefore the angular magnification of this thin lens is 2.94

Answer:
C
Explanation:
Work is when force is applied on an object and the object moves a certain distance as a result of that force.
Power = energy / time
Time should be in seconds
5 hours = 5 × 60 minutes = 5 × 60 ×60 seconds = 18000 s
Power = 6000/18000 = 0.333 W

The mass of the soil sample is 82g.
- The container has a mass of 15g.
- Let the mass of the soil be "x" g.
- The mass of the container and soil combined is 97g.
- container mass + soil mass = total mass
- 15g + x = 97g
- x = 97g-15g
- x = 82g
- The amount of matter that makes up a physical body is known as its mass. It serves as a gauge for the body's inertia.
- The amount of matter that makes up any item or body is the best way to define mass. Everything we see around us is made of mass.
- In physics, mass is the most fundamental characteristic of matter and one of the fundamental quantities. The amount of matter in a body is referred to as its mass. The kilogram is the kilogram, which is the SI unit of mass (kg).
