A compound optical microscope or just a optical microscope is a microscope that uses light and has more than one lens.
I think answer should be d. Please give me brainlest I hope this helps let me know if it’s correct or not okay thanks I appreciate it
Answer:
the magnitude of the velocity of the block just after impact is 2.598 m/s and the original speed of the bullect is 324.76m/s.
Explanation:
a) Kinetic energy of block = potential energy in spring
½ mv² = ½ kx²
Here m stands for combined mass (block + bullet),
which is just 1 kg. Spring constant k is unknown, but you can find it from given data:
k = 0.75 N / 0.25 cm
= 3 N/cm, or 300 N/m.
From the energy equation above, solve for v,
v = v √(k/m)
= 0.15 √(300/1)
= 2.598 m/s.
b) Momentum before impact = momentum after impact.
Since m = 1 kg,
v = 2.598 m/s,
p = 2.598 kg m/s.
This is the same momentum carried by bullet as it strikes the block. Therefore, if u is bullet speed,
u = 2.598 kg m/s / 8 × 10⁻³ kg
= 324.76 m/s.
Hence, the magnitude of the velocity of the block just after impact is 2.598 m/s and the original speed of the bullect is 324.76m/s.
Answer:
The object with the greater mass will have the greater momentum
Explanation:
The momentum of an object with mass <em>m</em>, moving with velocity <em>, </em>is given by the formula
M = <em>mv</em>
<em />
Since both objects have the same velocity <em>v, </em>it is clear that the object with the bigger mass will have the greater momentum
