Answer: force from sun to mars = 
, force from mars to sun = 
Explanation: The force of attraction or repulsion between 2 object ( in this case the sun and mars ) in space is given by newton's law of gravitation which is given mathematically below as
where 
G = gravitational constant, 
= mass of mars, 
= mass of sun
the mars also exerts the same magnitude of force above on the sun but in the opposite direction, thus the force mars exerts on the sun is
I'm taking test and believe its upward sloping line
The image is present at 20cm from the crown glass spherical surface.
To find the answer, we need to know about the lens formula.
<h3>
What's the lens formula?</h3>
- It's (1/V)-(1/U)= (1/f)
- V= image distance from the lens, U= object distance, f= focal length of the lens
<h3>What's the image distance, if object is present at 20cm from crown glass of power 10DS?</h3>
- Focal length (f)= 1/ power = 1/10 = 0.1 m
- U= -20cm = -0.2m (-ve sign due to sign convection)
- (1/V)-(-1/0.2)= (1/0.1)
=> (1/V)+5=10
=> 1/V= 5
=> V=0.2m = 20cm
Thus, we can conclude that the image is present at 20cm.

Answer:
95.47 C
Explanation:
Heat added = mass × heat capacity × rise in temperature
So, rise in temperature =
20000 / (0.05 × 4190)
Rise in temperature = 95.47 C
