This is triggered by an activity known as heliotropism, or solar tracking. Special motor cells at the bases of the flowerbuds shrink or enlarge as they absorb water, which moves their faces toward the sun.
Answer:
A
Explanation:
Hope this helps and have a wonderful day!!!
a = acceleration of the bank cart = 4 m/s²
m = mass of the bank cart = 8000 kg
F = net force on the cart
According to newton's second law , Net force is the product of mass of the object and the acceleration of the object.
Net force = mass x net acceleration
hence Net force acting on the cart is given as
F = ma
F = 8000 x 4
F = 32000 N
hence the net force acting on the cart comes out to be 32000 N
2. Write the chemical symbol of the atom.
1. Use the periodic table to find the chemical symbol of the atom and the number of electrons in the valence shell.
3.Draw dots around the chemical symbol to represent the valence electrons of the atom.
4. Count the dots to make sure that all of the valence electrons are represented.
Answer:
<h3>The answer is 20 N</h3>
Explanation:
The force acting on an object can be found by using the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 1000 g = 1 kg
acceleration = 20 m/s²
We have
force = 20 × 1
We have the final answer as
<h3>20 N</h3>
Hope this helps you
