Answer 1:


True


Explanation:


Especially, cars are intended to crush and consume some of the collision. However, they cant crumple too enough or our legs will get crushed also, which is not good. Its all based on the postulate that the force of the collision is less if the entire deceleration takes place over a prolonged duration of time. The car crumpling tries to increase the deceleration time.

Turn the ignition switch to start and release the key immediately or you could destroy the______________.
vredina [299]

Starter

Explanation:

Turn the ignition switch to start and release the key immediately or you could destroy the starter.

The car starter is used to cause ignition in the internal combustion engine in order to fire the piston and cause mechanical motion. The starter is used to start the cyclic process of the internal combustion engine.

  • Once the engine starts by igniting the starter, it is best to release it.
  • The starter ensures that the spark plug is engaged and the motor is brought into work.
  • If the ignition is still engaged, the process continues repeatedly and it can damage the starter of the car.

What is larger a Atom or a Molecule?
Kipish [7]
I believe an Atom is a very powerful source, the basic unit of a chemical element. An atom is a source of nuclear energy.


But a molecule on the other hand isn't so different.
a group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.
I hope that helps, have a fantastic day!

A baseball pitcher throws a ball at 97.0 mi/h in the horizontal direction. How far does the ball fall vertically by the time it
mario62 [17]

Answer:

Explanation:

1 mile=5280 ft

1 hour=3600 seconds

Changing speed from mi/h to ft/s

97 mi/h \times \frac {5280}{3600}=142.2666667 ft/s\approx 142.27 ft/s

Time of flight, t=\frac {distance}{speed}=\frac {60.5}{142.27}=0.425257732 s\approx 0.425 s

From fundamental kinematics equations

h=0.5gt^{2} where g is acceleration due to gravity whose value is taken as 32.2 ft/s2 and h is the distance

By substitution

h=0.5\times 32.2\times 0.425^{2}=2.9080625 m\approx 2.91 m
