\huge\mathfrak\red {Answer:}

<h2>Speed = Distance/Time</h2>

If a train travelled 500 meters in 25 seconds then,

Speed = 500m/25sec

<h2>→ 20 m/sec</h2>

I kinda don’t know how to solve this I need help.
NemiM [27]

Answer:

the answer is 11 N left

Explanation:

there is more force being applied in the direction left, so the ball will move left. to find the net force that the ball will move in that direction subtract the force being applied in the opposite direction. so, 16N-5N=11N. your answer in 11 N left.

stich3 [128]
-- Use the formula  D=(1/2)·(g)·(t²)  to calculate how long
it takes the flower pot to fall to the ground.

1.5 m = (1/2) · (9.8 m/s²) · (t²)

t² = (1.5 m) / (4.9 m/s²)

t = 0.554 second

-- Use the formula Distance = (speed)·(time) to calculate
how far the pot traveled horizontally in that amount of time.

Distance = (8 m/s) · (0.554 sec)

Distance horizontally = 4.43 meters

Review. Consider the deuterium-tritium fusion reaction with the tritium nucleus at rest:
asambeis [7]

Considering the deuterium-tritium fusion reaction with the tritium nucleus at rest: ¹₂H + ¹₃H → ²₄He + ⁰₁n  the electric potential energy (in electron volts) at this distance is 17.58MeV

<h3>How is the electric potential energy of deuterium-tritium fusion reaction calculated?</h3>

The reaction is  ¹₂H + 1₃H → ²₄He + ⁰₁n

Value of Q = (Mass of ¹₂H + Mass of ¹₃H - Mass of ²₄He- Mass of n) x 931 MeV

Mass of ¹₂H = 2.014102

Mass of ¹₃H = 3.016049

Mass of ²₄He = 4.002603

Mass of n = 1.00867

Therefore Value of Q = [2.014102+3.016049−4.002603−1.00867] × 931 MeV

Therefore Value of Q = 0.01887 × 931 MeV

= 17.58MeV
