Answer:
180 meters
Explanation:
We know initial position and velocity of the dragster are both zero. We only know acceleration (43 m/s^2) and need to find out how far the dragster moves after 2.9 seconds.
x initial = 0
velocity initial = 0
t=2.9s
a= 43m/s^2
Plug into
180 meters or 1.8 x 10^2 meters is the answer accounting for 2 sig figs.
Answer:
rate of infusion is 900 mL/hr
Explanation:
given data
Infuse I1 = 1000 mL
delivers = 15 gtt/mL
Infuse I2 = 300 mL
time t= 20 min
rate = 60 mL/hr
to find out
rate of infusion
solution
we know here we give 300 mL infuse in 20 min
so here for 20 min
rate of infusion is express as
rate of infusion = I2 / t
rate of infusion = 300 / 20
rate of infusion = 15 mL / min
rate of infusion = 15 × 60 = 900
so rate of infusion is 900 mL/hr
This suggest the the atom has a very small positively charged nucleus in the mass of the atom is concentrated.
And the electrons revolves around the nucleus in their orbits.
11m if you add 6+5 you get 11 but of course you need the “m” in the mix so 11m but correct me if I’m wrong.
Answer:
5.4 g
Explanation:
The stone is already in motion, so the only energy it has is kinetic. The formula for kinetic energy is:
You can substitute the 390 J in for KE and 12 m/s in for v. After that, the equation looks like:
Then do basic algebra and m=5.4 g
