Using Newton's second law of motion:
F=ma ; [ F = force (N: kgm/s^2);m= mass (kg); a = acceleration (m/s^2)
Given: Find: Formula: Solve for m:
F: 2500N mass:? F=ma Eq.1 m=F/a Eq. 2
a= 200m/s^2
Solution:
Using Eq.2
m= (2500 kgm/s^2)/ (200m/s^2) = 12.5 kg
When an atom has a high neutron-to-proton ration, that atom is very unstable and thus, radioactive. The more neutrons an atom has, the more radioactive it is. So,it is only logical that the element with the greatest number of neutrons is Uranium. It has 140 neutrons.
<h2>
Final velocity is 13.37 m/s</h2>
Explanation:
We have equation of motion v = u + at
Initial velocity, u = 7.3 m/s
Final velocity, v = ?
Time, t = 7.4 s
Acceleration,a = 0.82 m/s²
Substituting
v = u + at
v = 7.3 + 0.82 x 7.4
v = 13.368 m/s
Final velocity is 13.37 m/s
Pluto is the last so called planet so i am rambling on bc this website make me its Pluto
"1 watt" means 1 joule of energy per second.
75 W means 75 joules/sec .
Energy = (75 Joule/sec) x (12 min) x (60 sec/min)
Energy = (75 x 12 x 60) (Joule-<em>min-sec</em> / <em>sec-min</em>)
<em>Energy = 54,000 Joules</em>
