X≤10: The definition of nuclear fusion says: a reaction in whicih 2 OR MORE atoms come close enough together to form one or more different atomic nuclei and subatomic particles.
x=the number of atoms at the end
Answer: That is to say, a satellite is an object upon which the only force is gravity. Once launched into orbit, the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.
Explanation: Because Earth-orbiting objects follow elliptical paths around Earth and not a straight line, forces cannot, by definition, be balanced. Force is directional. It is a push or a pull in a particular direction.
Answer:
Idk but that is concerning and do you have a cat??
Explanation:
Answer:
77.08 C
Explanation:
= mass of the water = 500 g = 0.5 kg
= specific heat of water = 4186 J/(kg °C)
= Rate of change of temperature = 3 °C /min = (3/60 ) °C /s = 0.05 °C /s
= thermal conductivity of glass = 0.84
= Area of the element = 0.090 m²
= thickness of the element = 1.5 mm = 0.0015 m
= Temperature inside = 75 °C
= Temperature outside = ?
Using conservation of energy
Heat gained by water = Heat transferred through glass
The rocket would have gone 125 m away in deep space.The speed when it has gone 300 m is 76.7 m/s.
Answer:
The distance the rocket traveled is 125 m. The speed when it has gone 300 m is 76.7 m/s.
Explanation:
According to the equations of motion, if an object is moving with constant acceleration, then the distance travelled by the object with that acceleration and within a specific time can be obtained as
Since the initial velocity is given as u = 0 at t = 0. Then at t = 10 s, the acceleration is given by 2.5 m/.
Thus,
s= 0 + (×2.5×)=125 m.
Thus, the rocket would have gone 125 m away in deep space.
Similarly, if it had gone 300 m then its speed can be determined using the third equation of motion.
Since, here v is unknown and u is known as 0 with a = 2.5 m/.
2× 9.8×300=v²
5880=v²
Thus, the speed v =
So, the speed when it has gone 300 m is 76.7 m/s.
