Answer:
When elements bond together or when bonds of compounds are broken and form a new substance
Explanation:
Answer:
2.1406 ×
m/sec
Explanation:
we know that energy is always conserved
so from the law of energy conservation
here V is the potential difference
we know that mass of proton = 1.67×
kg
we have given speed =50000m/sec
so potential difference 
now mass of electron =9.11×
so for electron
so the velocity of electron will be 2.1406× m/sec
<span>The answer is 6 Joules. The kinetic energy (KE) of an object is the product of half of the mass (m) of the object and the square of its velocity (v²): KE = 1/2m*v². We know that m = 0.75 kg and that v = 4 m/s. Therefore, KE = 1/2 * 0.75 kg * (4 m/s)² = 1/2 * 0.75 kg * 16 m²/s² = 6 kg*m²/s² = 6 J.</span>
Vertical component = 2.25 N downward
Horizontal component = 1.05 N to the right
Magnitude of the net force = √ (2.25² + 1.05²)
= √6.165 = 2.483 N (rounded)
Direction of the net force = tan⁻¹ (1.05/2.25) to the right of downward
= tan⁻¹ ( 7/15 ) to the right of downward
= 25° to the right of downward (rounded)
Explanation:
The X chromosome (females have 2 of them while males have 1) is five times larger than the Y chromosome and has 10 times the number of genes.
