Explain why does the bowling ball decelerate as it travels along the lane

1 answer:

5 0

The main cause of this is Friction. The more oil that is laid down, the less friction there is between the ball and the lane surface. The less friction, the harder it is for the bowler to send the ball in a curved path imparted by the spin that the bowler puts on the ball at the instant of release.

A car starts from rest, speeds up with constant acceleration, and travels 400 meters in 10 seconds. What was the acceleration of

PIT_PIT [208]

Answer:

Acceleration of the car will be $a=8m/sec^2$

Explanation:

We have given that car starts from rest so initial velocity of the car u = 0 m/sec

And car traveled 400 m in 10 sec

So distance traveled by car s = 400 m

Time taken to compete this distance t = 10 sec

We have to find the acceleration of the car

From second equation of motion we know that $s=ut+\frac{1}{2}at^2$

So $400=0\times 10+\frac{1}{2}\times a\times 10^2$

$a=8m/sec^2$

So acceleration of the car will be $a=8m/sec^2$

In a semiclassical model of the hydrogen atom, the electron orbits the proton at a distance of 0.053 nm. part a what is the elec

Anestetic [448]

Potential energy is energy that is found in a system, grounded on the position of objects. The Coulomb (C) is the unit of charge, and the unit of electric potential is the Volt (V), which is equivalent to (J/C) or Joule per Coulomb.So the formula for this is potential = kQ / d, plugging in the given from the questions will give us:potential = 8.99e9N·m²/C² * 1.602e-19C / 0.053e-9m = 27 V

Which of the following statements is NOT true about absorbents used to soak up different leaks and spills? A) They may be pickin

cricket20 [7]

The correct option is D.
Absorbents are products which are principally designed to soak up spills and leaks. There are different types of absorbents and they are designed to absorb different substances. The absorbents are typically equipped with specific features which make them suitable for absorbing specific substances. Thus, one can not mixed up different absorbent for use. Most absorbents are designed to soak up oil spills.
