Answer:
The left train travels 2378 m until it reaches the meeting point.
Explanation:
The equation for the position of the trains is the following:
x = x0 + v · t
Where:
x = position at time t
x0 = initial position
v = velocity
t = time
If we place the origin of the frame of reference at the initial position of the left train, the right train will be at an initial position of 4744. 6 m relative to the left train. The velocity of the right train will be negative because it will be heading towards the origin.
At the meeting point, the position of both trains is the same:
x left train = x right train
x0₁ + v₁ ·t = x0₂ + v₂ · t
0m + 29 m/s · t = 4744.6 m - 29 m/s · t
58 m/s · t = 4744.6 m
t = 4744.6 m / 58 /s
t = 82 s
The position of the left train at that time will be:
x = x0 + v · t
x = 0 m + 29 m/s · 82 s
x = 2378 m
The left train travels 2378 m until it reaches the meeting point.
Answer:
By heating all the water molecules which changes the thermal energy of the food
Explanation:
Answer:
7.77 x 10⁸ Km
Explanation:
given,
Speed of light = 3 x 10⁵ Km/s
= 3 x 10⁸ m/s
1 light hour = 1.079 x 10⁹ Km
now,
0.72 light hour = 0.72 x 1.079 x 10⁹ Km
= 0.7769 x 10⁹ Km
= 7.77 x 10⁸ Km
The Jupiter is 7.77 x 10⁸ Km far from sun.
It would be the electromagnet because that is how it spins
An elastic collision<span> is where there is no loss of kinetic energy in the </span>collision<span>. Momentum is conserved saved in </span>inelastic collisions<span>, but cannot track the kinetic energy through the </span>collision<span> since some of it is changed into other forms of energy.</span>
