Answer:
461.88 N
Explanation:
Let tension in each vine be T .
The vertical component of this tension of both the vine will add up and balance the weight .
2T cos 30 = mg
2 T x cos 30 = 800
T = 800 / (2 x cos30 )
= 461.88 N
Neptunes' average density is larger than that of Uranus. Hope this helps!
Answer:
a)A= 3 m
b)
c)D= 15 m
Explanation:
Given that
v= 3 m/s
a)
The amplitude(A) of the pulse :
When x= 0 ,Then y = A
Put x= 0
y= A= 3 m
A= 3 m
b)
Distance travel in time t
x= vt
x= 3 t
c)
The distance covered by pulse in the time 5 s
D = v t
D= 3 x 5
D= 15 m
<u>Given</u><u> </u><u>-</u><u> </u>
- Velocity (v) = 12.1 m/s
- Time (t) = 8.2 sec
<u>To</u><u> </u><u>find</u><u> </u><u>-</u>
<u>Solu</u><u>tion</u><u> </u><u>-</u><u> </u>
★ Acceleration = velocity/ time
→ A = 12.1/8.2
→ 1.47.... m/s²
