Answer:
Keep on moving
Explanation:
Newton's first law states "that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force."
Answer:
zero
Explanation:
For a solid conducting sphere, charges are present on the surface of the sphere due to a phenomenon known as electrostatic sheilding. This affects the charge present in the body and makes it zero. However, the electrostatic potential appears to be equal to the whole present point that shows on the surface. The surface of a spherical conducting solid sphere is known as an equipotential surface. Thus, the potential difference between the two opposite points on the surface of the sphere will also be zero.
To solve this problem we will apply the definition of the ideal gas equation, where we will clear the density variable. In turn, the specific volume is the inverse of the density, so once the first term has been completed, we will simply proceed to divide it by 1. According to the definition of 1 atmosphere, this is equivalent in the English system to
The ideal gas equation said us that,
PV = nRT
Here,
P = pressure
V = Volume
R = Gas ideal constant
T = Temperature
n = Amount of substance (at this case the mass)
Then
The amount of substance per volume is the density, then
Replacing with our values,
Finally the specific volume would be
Answer:
The flow speed at 2.6 cm diameter pipe is 1.2
Explanation:
Given :
Speed at 4 cm diameter pipe
Area of 4 cm diameter pipe
Area of 2.6 cm diameter pipe
From the equation of continuity,
Find the speed at 2.6 cm diameter pipe,
Therefore, the flow speed at 2.6 cm diameter pipe is 1.2

Hazardous waste are actually defined as RCRA in 40 CFR 261 the the four hazardous traits are
ignitability
reactivity
corrosivity
toxicity
