Answer:
32 ms
Explanation:
v=32ms.
Explanation:
I will assume that you mean that the acceleration is 8.0 ms2, as 8.0ms is a value for velocity, not acceleration.
Here, we use the formula v=u+at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is time. Let's substitute values, then:
v=u+at,
v=0+8.0⋅4.0
v=32,
v=32ms.
Hope it Helps! :D .
Answer: W = 0.3853 J, e = 0.052 m
Explanation: Given that,
K =285.0N/M , L = 0.230m , F = 15N , e = ?
F = Ke
15 = 285 × e
e = 15÷ 285
e =0.052 m
e + L = 0.052 + 0.230
= 0.282m ( spring new length )
Work needed to stretch the spring
W = 1/2ke2
W = 1/2 × 285 x 0.052 × 0.052
W = 0.3853 J
Answer:
a) h = 8.02 10³ m b) yes
Explanation:
a) The pressure in a fluid is given by
P = ρ g h
The pressure in this case is the atmospheric pressure, 1.013 105 Pa, let's clear the height (h)
h = P / ρ g
h = 1.013 10⁵ / (1.29 9.8)
h = 8.02 10³ m
b) The height of Mount Everest is 8848 m
It is above this height, according to this model there would be no air to breathe
The vaccine ofcourse. They helped in making the vaccine.
Im guessing it's (a) since the numbers go in chronological order and you read the periodic table left to right
