Answer:
no one says it that but
in hirosima their are 70000 people die instant
Explanation:
It is given that,
Mass of moon,
Radius of circle,
The time required for one revolution is 27.3 days, t = 27.3 days
1 day = 86400 seconds
27.3 days = 2358720 seconds
Let v is the speed of moon around the circular path. It is given by :
v = 1017.57 m/s
Let F is the centripetal force acting on the moon. It is given by :
So, the centripetal force that must act on the moon is . The gravitational force that the earth exerts on the moon at that same distance is also equal to . Hence, this is the required solution.
Both involve the formation of a gas.
energy.
Calculate the original kinetic energy of the electron. [Show all work, including the equation and
substitution with units.]
K.E =2.85 × 10⁻¹⁸ Joules.
K.E = 1/2 mv²
Mass of an electron = 9.11 × 10⁻³¹ Kg, velocity of the electron =2.5×10⁶ m/s
Thus, K.E = 1/2 (9.11 × 10⁻³¹ Kg) (2.5 × 10⁶ m/s)²
= 2.85 × 10⁻¹⁸ Joules.
The original kinetic energy of this electron is equal to 2.85 × 10⁻¹⁸ Joules.
Given the following data:
Scientific data:
Mathematically, kinetic energy can be calculated by using this formula:
K.E = 1/2 × mv²
Where:
Substituting the given parameters into the formula, we have;
K.E = 1/2 × 9.11 × 10⁻³¹ × (2.5 × 10⁶ m/s)²
K.E = 2.85 × 10⁻¹⁸ Joules.
