Kg . Meter per second (Kg.m/s)
The impact speed will be
v^2 = 2*9.8*1.3
v^2 = 25.48
v= 5.04 m/s
An unglazed piece of porcelain, used to test the characteristic streak of minerals by rubbing the mineral across the tile. Streak plates have a hardness of about 6.5 on the Mohs scale and cannot be used for testing harder minerals.
Complete question is;
Describe how α-radiation is similar to β-radiation?
Answer:
Explained below
Explanation:
The similarity between both alpha radiation and beta radiation is that in both cases, they both show deflection when they go through electric and magnetic fields. Although alpha deflects towards the negative plate while bets deflects towards the positive plate.
Secondly they both have high speeds. Just that alpha is from the helium nucleus while beta is from electrons.
Answer:
Explanation:
1. 
= 
* cos
⇒ 16*cos32 ≈ 13.6 m/s (13.56)
2. 
= * sin ⇒ 16* sin32 ≈ 9.4 m/s
3. 
= 
= 
(the g (gravity) depends on the country but i'll take the average g which is 9.2m/s^2)
≈ 3.6677+1.5 ≈ 5.2m
4. 
= 
=
≈ 23.5m (23.47)
5. -
answer 4 could be wrong, not certain about that one and i don't know 5
