Image distance (Di) = 17 cm
Object distance (Do) = 36 cm
Using mirror equation,
1/Di + 1/Do = 1/f
1/17 + 1/36 = 1/f
0.058824 + 0.027777 = 1/f
1/f = 0.086601
f= 11.5472 = 11.55 cm
Answer:
Acclⁿ = 18m/s² .
Explanation:
Mass = 10 kg
Frictional force is acting in opposite dirⁿ . Therefore the net force will be ,
=> F_net = 200N - Fricⁿ force
=> m * a_net = 200N - u mg
=> 10kg *a_net = 200N - 0.2*10*10
=> a_net = 180/10 m/s²
=> a_net = 18m/s²
The shadow forms on the first surface away from the shuttle in the direction opposite the sun.
Gravitational potential energy can be calculated using the formula <span>PE = m × g × h, where g is the gravitational acceleration and is constant hence the energy is dependent directly to mass and the height of the object. Hence more PE is registered when the object is heavier and/or at greater initial height. </span>
Electromagnetic waves are used in everyday life. You are looking at your computer screen right now. The light that is coming off of the screen is visible light, a form of electromagnetic radiation. Electromagnetic waves are also used to send information. For example, AM or FM radios are radio waves that transfer sound information to your local radio.
