Answer:
6.83 cm
Explanation:
Given data:
Focal length of the eye piece, = 2.50 cm
Focal length of the converging lens, f = 1.00 cm
distance of the object, p = 1.30 cm
Now,
we have the lens equation as:
q is the distance of the image
thus,
on substituting the values in the above equation, we get
or
q = 4.33 cm
now, the image is formed at the focal point of the eye piece,
therefore, the distance between the objective and the eyepiece, d = + q = 2.50 cm + 4.33 cm
or
d = 6.83 cm
Answer:
v = ((m + M) / m)*√(2*g*h)
Explanation:
Given
m = mass of the projectile
M = mass of the ballistic pendulum
v = initial speed of the projectile
v' = speedof the system (pendulum + projectile) after the inelastic collision
h = maximum height reached for the system
Knowing that is an inelastic collision we have
m*v + M*(0) = (m+M)*v'
⇒ v' = m*v / (m+M)
After the collision, we apply the Principle of the Conservation of Energy
Ki + Ui = Kf + Uf
where
Ui = Kf = 0 J
then
Ki = Uf
0.5*(m+M)*v'² = (m+M)*g*h
⇒ 0.5*v'² = g*h
⇒ v'² = 2*g*h
⇒ (m*v / (m+M))² = 2*g*h
⇒ v = ((m+M) / m)*√(2*g*h)
