I believe the correct answer from the choices listed above is option C. The units for the specific heat capacity or C would be J/g °C. It is <span>the heat required to raise the temperature of the unit mass of a given substance by a given amount .</span>
About what elemental trip through europe
Answer:
Point C
Explanation:
Centripetal acceleration ac is inversely proportional to radius of orbit so it is greatest at point C.
(1) directed to the right
Explanation:
To the right of B, u(x) is a decreasing function & so its derivative is negative,this implies that the x component of the force on a particle at this position is positive,or that the force is directed towards right .Small deviations from equilibrium at point B causes a force to accelerate the particle away ,hence particle is in <u>unstable equilibrium.</u>
Answer:20.82 m
Explanation:
Given
distance between wall and launcher=5 m
initial velocity=30 m/s
Launching angle
Height of wall=12 m
maximum height by ball
h=22.95 m
y=4.72 m
so ball will strike with wall
and for perfect restitution final velocity of ball will be same as the horizontal velocity before its impact, only direction will be opposite and vertical velocity will be zero
thus it seems as if someone throw the ball with horizontal velocity of 30cos45 from a height of 4.72
Time required to cover 4.72 m
t=0.981 s
Horizontal distance traveled in this time
R=20.82 m
