How are distance and displacement different?

1 answer:

7 0

Distance is a scalar as it provides magnitude without direction
Ex. 5 m

Displacement is a vector as it has magnitude and direction
Ex. 5 m [N]

Make the following conversion. 34.9 cL = _____ hL. 0.349 0.0349 0.00349 349,000

AnnyKZ [126]

Hey there!

Here is your answer:

The proper answer to this question is option C "0.00349".

Reason:

1 L = 100 cL. Or 1 cL = 0.01 L

34.9 cL = 34.9 / 100 L = 0.349 L

 1 hL = 100 L. 0.349 L = 0.349 / 100 hL = 0.00349 hL

Therefore the answer is option C!

If you need anymore help feel free to ask me!

Hope this helps!

The 5-kg block A has an initial speed of 5 m/s as it slides down the smooth ramp, after which it collides with the stationary bl

Akimi4 [234]

Answer:

The coupled velocity of both the blocks is 1.92 m/s.

Explanation:

Given that,

Mass of block A, $m_1=5\ kg$

Initial speed of block A, $u_1=5\ m/s$

Mass of block B, $m_2=8\ kg$

Initial speed of block B, $u_2=0$

It is mentioned that if the two blocks couple together after collision. We need to find the common velocity immediately after collision. We know that due to coupling, it becomes the case of inelastic collision. Using the conservation of linear momentum. Let V is the coupled velocity of both the blocks. So,

$m_1u_1+m_2u_2=(m_1+m_2)V\\\\V=\dfrac{m_1u_1+m_2u_2}{(m_1+m_2)}\\\\V=\dfrac{5\times 5+0}{(5+8)}\\\\V=1.92\ m/s$

So, the coupled velocity of both the blocks is 1.92 m/s. Hence, this is the required solution.
