Gravitational acceleration is approx 9.8 m/s
Time is 7s
a=9.8 m/s
t=7s
a = d/t^2
therefore:
d = a * t^2
d = 9.8 * 7^2
d = 9.8 * 49
d = 480.2 [m]
Answer:
Area of the rectangular field in kilometers is 0.09
Explanation:
We know that 1 kilometers = 1000 meters
since we need to find the area in unit of kilometers
therefore converting length and width into kilometers
1000 meters = 1 kilometers
300 meters =
Likewise width = 0.3 km
Area = length x width
= 0.3km x 0.3 km
= 0.09
Magnetic fields can go through some materials (like cardboard). Electric fields can also do that. Electromagnetic waves can do that. It’s not at all unusual because magnetic fields are not made up of particles so they can go through materials.

for water,
For bromine
Divide (i) and (ii)
Put the density value in equation (i)
Just like sedimentary rocks, metamorphic rocks can be forced to the Earth's surface too. ... All this movement can cause rocks that were once underground to be brought up to the Earth's surface. This process is called uplift. Once exposed to the elements the rock on the Earth's surface begins to weather and erode.
