<u>Answer</u>
Immune system
The body’s defense against germs and diseases is called the immune system. The immune system consists of network cells which work together to protect the body
Kinetic energy is related to velocity by:
KE = (1/2)mv^2
solve for mass m
10 = (1/2)m(10)^2
10 = (1/2)m(100)
10= 50m
10/50 = m
1/5 = m
at 20 km/hr
KE = (1/2)(1/5)(20)^2
KE = (1/10)(400)
KE = 40 J
Explanation:
she ends up with a displacement of 5km north of her house and a distance of 3km
Answer:
The electron
Explanation:
The atom consists of three subatomic particles:
- The proton: protons are inside the nucleus of the atoms, they have positive charge of +e (), and a mass of approximately
- The neutron: neutrons are also located inside the nucleus of the atoms, they have no electrical charge and mass similar to the mass of the proton
- The electron: electrons orbit around the nucleus in a cloud, they have negative charge of -e (), and their mass is about 1800 time smaller than the mass of the proton ()
Answer:
film is at distance of 3.07 cm from lens
Explanation:
Given data
focal length = 3.06 cm
distance = 10.4 m = 1040 cm
to find out
How far must the lens
solution
we apply here lens formula that is
1/f = 1/p + 1/q
here f = 3.06 and p = 1040 so we find q
1/f = 1/p + 1/q
1/3.06 = 1/1040 + 1/q
1/ q = 0.3258
q = 3.0690 cm
so film is at distance of 3.07 cm from lens
