Answer:
A study looking at how alcohol consumption impacts the brain. A study to discover the components making up human DNA. A study accessing whether stress levels
Explanation:
For example, a scientist that tries to figure out how the body makes cholesterol, or what causes a particular disease, is performing basic scienc
Momentum equation is
change in momentum = mass•initial velocity•final velocity
so....
p=700(15) because your initial is 30, and your final in 15, so you subtract! hope that helped!
Velocity of proton= 4782 m/s
Explanation:
For proton, the centripetal force required for circular motion is provided by the magnetic force,
so Fm= Fc
q v B = m v²/r
m= mass of proton
v= velocity
B =magnetic field=0.05 T
q= charge= 1.6 x 10⁻¹⁹
r= radius = 1 mm =0.001 m
v= q B r/m
V= (1.6 x 10⁻¹⁹)(0.05)(0.001)/(1.673 x 10⁻²⁷)
V= 4782 m/s
Answer:
b) 1500N
c) to the right
Explanation:
Resultant force= 2000 -500= 1500N
Resultant force is a combination of 2 or more forces acting on an object.
