Answer:
0 m/s^2
Explanation:
Use a formula to answer the question
d = r * t
The object is not changing speed at any time, or if it is we are not told. The rate is the speed.
8 = r * 1 second
8 m/sec = r
The initial speed is 8 and the final rate is 8. There is no change. So when you use this formula
a = (vf - vi)/t we get a = (8 - 8)/1 = 0
There is no acceleration because there is no change in speed.
Answer:
Explanation:
A) Hg is mercury, a metal that is mostly liquid at STP (Standard Temp and Pressure), though some small portion of it will be gaseous in a closed container.
B) CH Methylidyne radical is a gas
It is not a stable compound because carbon has four valence electrons and only one of those is kept occupied by the hydrogen atom.
If this is supposed to be CH₄ which is methane, then also a gas at STP
C) C₂H₅OH is ethanol which is mostly a liquid at STP, though some small portion of it will be gaseous in a closed container.
D) H₂O is water and will be mostly liquid at STP, though some small portion of it will be gaseous in a closed container.
Answer:
The condition necessary for the person to be able to remain stationary in mid-air is that there must be an upward force also referred to as THRUST
Explanation:
Thrust in Physics is defined as the force that propels, forces or pushes the mass of a certain object in a specified or particular direction.
Thrust can defined in the terms of a Jet pack can be defined as the force that is required to propel the mass of a person in an upward direction.
Based on the diagram that we have been shown the question, we can see that water is the fuel used to proper the user or person upwards hence, the jet pack used in the question is an HydroJet pack
The condition necessary for the person to be able to remain stationary in mid-air is that the propelling force called the thrust must be upwards such that it can overcome these 4 things:
a) Gravitational force
b) Mass of the jet pack user
c) Mass of the jet pack itself
d) The water which serves as fuel for the jet pack.
Answer:
Explanation:
The weaker force is pulling to direction East(450 newton)
the net force is (500-450=50 newton) and will move toward west ( in 500 newton direction)
