Answer:
a= 2.5m/s²
Explanation:
U=0
V=90km/hr
T= 10s
Convert 90km/hr to m/s
1km= 1000m
1hr= 3600s
(60×60)
therefore, 90km/hr = 90000/3600
90km/hr= 25m/s
From Newton First Equation,
V=U + AT
25=0+ A(10)
25= 10A
25/10 =10A/10
A= 2.5m/s²
With another person on student A’s side. I’m sorry if I wasn’t able to help. Im trying my best from the information given. :)
The only electromagnetic wave that human eye can see or sensitive are those of visible light waves. These are colors representing the color of rainbow(red, orange, yellow, green, blue, and violet). Red, which appears in the outermost shell of the rainbow, has the longest, wavelength, around 620-750 nm
Answer:
container of hydrogen gas has a volume of 2.3m³. What is the mass of hydrogen
Answer:
C
Explanation:
Diagram C is the correct answer, because the ball is at the point with the highest height relative to the ground, in this way all the kinetic energy has been transformed into potential energy.
We must remember that potential energy is defined as the product of mass by gravity by height
Ep = m*g*h
where:
m = mass [kg]
g = gravity acceleration [m/s²]
h = elevation [m]
So when we have a great value for h in the above equation, we will have a big value for potential energy.
