Answer:
9.7 ms⁻¹
Explanation:
The formula to find the acceleration is :
According to the question, we are asked to find the Final Velocity.
For that, let the Final Velocity be x.
Therefore,
Final velocity = 9.7ms⁻¹

Answer:
The velocity of the ball is 0.92 m/s in the downward direction (-0.92 m/s).
Explanation:
Hi there!
The equation for the velocity of an object thrown upward is the following:
v = v0 + g · t
Where:
v = velocity of the ball.
v0 = initial velocity.
g = acceleration due to gravity (-9.8 m/s² considering the upward direction as positive).
t = time.
To find the velocity of the ball at t = 0.40 s, we have to replace "t" by 0.40 s in the equation:
v = v0 + g · t
v = 3.0 m/s - 9.8 m/s² · 0.40 s
v = -0.92 m/s
The velocity of the ball is 0.92 m/s in the downward direction (-0.92 m/s).
It is a solid when is frozen and a liquid when it melts

Diameter = d = ?
Answer:
d = 38.6 cm
f = 1000
Explanation:
(a) What is the diameter of the largest orbit, just before the protons exit the cyclotron?
The radius and hence the diameter of the largest orbit can be found by using
r = mv
/|q|B
Where q = 1.60x10⁻¹⁹ C and m = 1.67x10⁻²⁷ kg and v is the speed of the particle which can be found by using
v = √2K
/m
Where K is the kinetic energy in Joules.
1 eV is equal to 1.60x10⁻¹⁹ J
K = 6.5x10⁶*1.60x10⁻¹⁹ = 1.04x10⁻¹² J
v = √2*1.04x10⁻¹²
/1.67x10⁻²⁷
v = 35.29x10⁶ m/s
r = 1.67x10⁻²⁷*35.29x10⁶
/1.60x10⁻¹⁹*1.9
r = 0.193 m
d = 2r
d = 2*0.193 = 0.386
or d = 38.6 cm
(b) A proton exits the cyclotron 1.0 ms after starting its spiral trajectory in the center of the cyclotron. How many orbits does the proton complete during this 1.0 ms?
The period T and frequency (number of rotations per second) are related as
f = 1/T
f = 1/0.001
f = 1000
Answer:
Gas is different from liquid. Liquid has a definite volume but takes the shape of the container it is in. Gas on the other hand, has no definite shape or volume.
