Stay away from water. Try not to wash, shower, wash dishes, or have some other contact with water during a thunderstorm because lightning can travel through a building's plumbing.
Further Explanation:
Be aware
Check the climate conjecture before taking an interest in outside exercises. In the event that the estimate calls for tempests, defer your excursion or movement, or ensure sufficient safe house is promptly accessible.
Go inside
Keep in mind the expression, "When thunder thunders, go inside." Find a protected, encased asylum when you hear thunder. Safe havens incorporate homes, workplaces, strip malls, and hard-top vehicles with the windows moved up.
Hunch near the ground and isolated
On the off chance that you are gotten in an open zone, hunker down in a ball-like position (feet and knees together) with your head tucked and hands over your ears so you are down low with insignificant contact with the ground. Try not to rests. Lightning causes electric flows along the highest point of the ground that can be fatal more than 100 feet away. Hunching down is the best mix of being low and contacting the ground as meager as could be expected under the circumstances.
Discrete
On the off chance that you are in a gathering during a rainstorm, separate from one another. This will decrease the quantity of wounds if lightning strikes the

Answer:
a) x_{cm} = m₂/ (m₁ + m₂) d
, b) x_{cm} = 52.97 pm
Explanation:
The expression for the center of mass is
= 1 / M ∑
Where M is the total masses, mI and xi are the mass and position of each element of the system.
Let's fix our reference system on the oxygen atom and the molecule aligned on the x-axis, let's use index 1 for oxygen and index 2 for carbon
x_{cm} = 1 / (m₁ + m₂) (0+ m₂ x₂)
Let's reduce the magnitudes to the SI system
m₁ = 17 u = 17 1,661 10⁻²⁷ kg = 28,237 10⁻²⁷ kg
m₂ = 12 u = 12 1,661 10⁻²⁷ kg = 19,932 10⁻²⁷ kg
d = 128 pm = 128 10⁻¹² m
The equation for the center of mass is
x_{cm} = m₂/ (m₁ + m₂) d
b) let's calculate the value
x_{cm} = 19.932 10⁻²⁷ /(19.932+ 28.237) 10⁻²⁷ 128 10-12
x_{cm} = 52.97 10⁻¹² m
x_{cm} = 52.97 pm
Explanation:
Acceleration is the change in speed over a given time period
Answer:
because the mass of the apple is very less compared to the mass of earth. Due to less mass the apple cannot produce noticable acceleration in the earth but the earth which has more mass produces noticable acceleration in the apple. thus we can see apple falling on towards the earth but we cannot see earth moving towards the apple.
