Explanation:
work = force ×distance
1 w = ? f= 200 d= 1.3
w = f ×d
=200×1.3
= 269 joule
2 w=? f=40. d=6
w= 40/6
= 240 joule
3. w=? m=254. f= ? d=3
w=f=mg. f= 254×10. f= 2540
w=f×d
=2540×3
= 7620 joule
You can use conservation of momentum, Ramon has a momentum of m * v = 59.0 * 1.20 = 70.8. James must have that same momentum so m * v = p -->
p / m = v --> 70.8 / 85.0 = 0.83 m/s for James
Answer:
arctg (- 6.5 / 6.0) = -47.2906° ~ 47
Ans. 360° - 47°= 133°
Concave Mirror is a mirror with a curved reflecting surface that is bulging inward. This is the opposite of Convex Mirror which has a bulging outward surface. Concave mirrors are also called converging mirrors. The concave mirror reflected the light inward to a single focal point. These are usually used in reflecting telescopes.
Answer:
The lithosphere is divided into huge slabs called tectonic plates. The heat from the mantle makes the rocks at the bottom of lithosphere slightly soft.
