Answer: 8
Explanation:
Non metals which have 4 electrons in the outer shell i.e in the valence shell bond with the other similar non metals having 4 electrons in their valence shell. This bond is known as covalent bond in which the two atoms share their valence electrons with each other in order to complete their valence shell. These atoms seeks to have 8 electrons in order to attain noble gas configuration.
Answer:
c it does not move as the tire stops and applys friction
Explanation:
Work done = force x distance
Work done = 50 x 2
Work done = 100J
It will be 133 on the moon
Answer:
2.572 m/s²
Explanation:
Convert the given initial velocity and final velocity rates to m/s:
- 65 km/h → 18.0556 m/s
- 35 km/h → 9.72222 m/s
The motorboat's displacement is 45 m during this time.
We are trying to find the acceleration of the boat.
We have the variables v₀, v, a, and Δx. Find the constant acceleration equation that contains all four of these variables.
Substitute the known values into the equation.
- (9.72222)² = (18.0556)² + 2a(45)
- 94.52156173 = 326.0046914 + 90a
- -231.4831296 = 90a
- a = -2.572
The magnitude of the boat's acceleration is |-2.572| = 2.572 m/s².
