the actual answer is C i did it on usatestprep
Explanation:
Answer:
I know someone anwsered but it would be 400M
Explanation:
i initial velocity (u)=10m/s
acceleration (a)=0
time taken (t) =40s
then distance (s)=u t +1/2 a t^2
s= u t +0 (as a is 0)
s= 10 x 40
s= 400M
Answer: C. Some of uranium's mass is converted into energy, so the smaller atoms have less mass.
Explanation:
From Einstein's mass-energy relation:
E = mc²
Mass and energy are equivalent. Mass can be converted into energy and energy into mass.
When Uranium atoms under go nuclear fission, smaller atoms are formed and huge amount of energy is released. This energy comes from the mass difference of the uranium nuclei and new nuclei formed. This mass converted into energy according to Einstein's equation.
I dont know what the statements are but concave lens are thinner in the middle which cause light to diverge or scatter
Answer:
12 m/s
Explanation:
Given data
Mass m= 1500kg
intitial velocity u= 20m/s
force F= 6000N
time t= 2 seconds
Required
The final velocity v
From
Ft= mΔv
Ft= m(u-v)
substitute
6000*2= 1500(20-v)
solve for v
12000= 30000- 1500v
collect like terms
12000-30000= -1500v
-18000= -1500v
divide both sides by -1500v
v= 18000/1500
v=12 m/s
Hence the velccity is 12 m/s
