When it rains, the growth aids in the soil drift
Explanation:
Bromine Br−1 has 35 protons, 36 electrons and 45 neutrons
If force is applied at 30 degree with the horizontal
then first we will find the components of force in two directions


now we can find normal force by balancing the forces in Y direction




now since block is moving with constant speed
so here forces along horizontal plane will be balanced also



Now the weight of the box is defined as

now plug in all values

Answer:
Option 2 is the correct answer.
Explanation:
We have equation of motion s = ut + 0.5at²
Here u = 0 m/s
So, s = 0.5at²
Distance traveled in first second = 0.5 x a x 1² = 0.5 a
Distance traveled in second second = 0.5 x a x 2² - 0.5 x a x 1²= 1.5 a
Distance traveled in third second = 0.5 x a x 3² - 0.5 x a x 2²= 2.5 a
Distance traveled in fourth second = 0.5 x a x 4² - 0.5 x a x 3²= 3.5 a
The percentage increase in its displacement during the 4th second compared to its displacement in the 3rd second

Option 2 is the correct answer.
