Answer: K =24 psi
Explanation:
Given: Standard deviation =3psi
Internal pressure strength =157psi
Number of random bottle =n=64
K= 3 × square root of 64
K= 3×8=24 psi
If mean internal pressure K fall below K,
157-1.3=155.7psi
At 2%:
0.16×64 = 10.24
Answer:
9.22 m/s
Explanation:
Vertical height, y = 36 m
Horizontal distance, d = 25 m
Let the initial velocity of projection is u and it is projected horizontally.
Let t be the time taken by the ball to hit the ground.
For horizontal motion
horizontal distance = horizontal velocity x time
d = u x t
25 = u x t .... (1)
Use second equation of motion for vertical direction
y = 0.5 x g t², as the initial vertical velocity is zero.
36 = 0.5 x 9.8 x t²
t = 2.7 second
Put in equation (1)
25 = u x 2.7
u = 9.22 m/s
Thus, the initial velocity with which the ball is projected horizontally is 9.22 m/s.
Answer:222 meters
Explanation:
Speed=80kph=(80x5/18)=(80x5)/18=22.2m/s
Time=10 seconds
distance=speed x time
distance=22.2 x 10
distance=222
distance=222 meters
Answer:
The simplest cells are made up of plates of two different kinds of metal, which are kept in salty or acid liquid. When a wire connects the two plates, electrical current flows between them.
