Answer:
If it was close we would die.
Explanation:
Probably has something to do with the earths original formation.
The Earth orbits the sun constantly, continuously, and all the time. " 24/7/365 "
From the sun's point of view, it takes the Earth roughly 365 and 1/4 days
to make the complete trip, all the way around one time. That's the length
of time that we call "one year".
When you talk about orbiting in one month, you're thinking of the moon
orbiting the Earth. THAT length of time is about 27.32 days.
Si velocidad es de 5m/s y esta recorriendo un parke de un tamaño de 7.2 kilometros, su recorrido le duro 1 hora y 44 minutos.
Dividi los kilómetros del parque por la velocidad, dándomela la hora que duró su recorrido
7.2÷5=1.44
Answer:
45 N
Explanation:
The question can be solved by using Newton's second law:
F = ma
where
F is the net (unbalanced) force on the cyclist
m is the mass of the cyclist
a is his acceleration
In this problem:
m = 50 kg

Therefore, the unbalanced force is

Answer:
Explanation:
Inital KE = (1/2) m v^2 = (1/2) * 1500 * 50^2 = 1,875,000 J
Final KE = (1/2) * 1500 * 100^2 = 7,500,000 J
But ,
4 * 1875000 = 7500000
so the KE has increased by 4 times.
