We have to convert Gm/s to m/s.
As
Therefore the speed of light in vacuum,
Thus, the speed of light in m/s is
Answer:
118 N
Explanation:
Given mass of the block, m = 4.00kg.
The acceleration of the elevator, a = 3.0 m/s^2.
As elevotar attaced with spring scale and accelerating upward
(block and elevator), so total force
Here, mg is the weight of the block downward direction.
or
substitute the given value, we get
= 117.6 N = 118 N.
Thus, the reading on the spring scale to 3 significant figures is 118 N.
Answer:
It is given that the weight of the person is 102 N
We have the force that shall be needed to being the man out in minimum amount of time shall correspond to the maximum tension that can be developed
Thus using Newton's second law we obtain the acceleration that the man shall attain
Now using second equation of kinematics to obtain time 't' we get
Answer:
v=1.26 m/s
Θ=81°NE
Explanation:
Linear momentum is the product of the mass and velocity of an object.
Dog's momentum can be hold using its mass and velocity:
m=26.2kg
v=3.21 m/s
(kg⋅m/s)
same thing with the cat
m=5.30kg
v=2.64m/s
(kg⋅m/s)
owner's momentum
p =13.992 m/s i + 84.102 m/s j
divide by mass to get velocity:
v = 0.20m/s i + 1.25 m/s j
mag v = √(0.20² + 1.25²) m/s = 1.26 m/s
Θ = arctan(1.25/0.2) = 81º north of east
Answer:
The chemical is the same but the concentration is different.
The chemical is more dangerous in its highly concentrated form.
Although the chemicals are the same, they require different handling procedures. Therefore specific information should be available for each.
