A car traveling at 70 mph70 mph down the interstate collides with a bug trying to cross the highway. Which of the following stat

ements best describes this collision? The car exerts a smaller force on the bug than the bug exerts on the car. The car exerts a larger force on the bug than the bug exerts on the car. Neither exerts a force on the other. The bug gets smashed because it got in the way of the car. The car exerts a force on the bug but the bug does not exert a force on the car. The car exerts the same sized force on the bug as the bug exerts on the car.

The force exerted by the car on the bug is identical to the force the bug applies back on the car.

Two very small 8.55-g spheres, 15.0 cm apart from center to center, are charged by adding equal numbers of electrons to each of
ValentinkaMS [3465]

Answer:

1.43 x 10¹⁷.

They will move away from each other.

Explanation:

The force acting on each charged sphere is determined as F = mass x acceleration

= 8.55 x 10⁻³ x 25 x 9.8

= 2.095 N

Assuming Q is the charge on each sphere

F = \frac{9\times10^9\times Q^2}{(15\times10^{-2})^2}

Using the values, 2.095 = \frac{9\times10^9\times Q^2}{(15\times10^{-2})^2}

We find that Q² = \frac{2.095\times(15)^2\times10^{-4}}{9\times10^9}

Thus, Q = 2.289 X 10⁻⁶

The quantity of electrons = Charge / charge of a single electron

= \frac{2.289\times10^{-6}}{1.6\times10^{-19}}

=1.43 x 10¹³.

They will accelerate away from each other.

Which model is used to describe the interaction of external forces that affect an organization's strategy and ability to compete
ValentinkaMS [3465]

Answer:

Competitive forces model

Explanation:

The Competitive forces model is a crucial instrument in strategic analysis aiming to assess an organization’s competitiveness. Commonly referred to as the "Five Force Model of Porter", this framework includes five key factors: the intensity of rivalry among existing competitors, the negotiating power of buyers, the threat posed by potential new entrants, the bargaining strength of suppliers, and the risk of substitute products or services.

These elements significantly influence an organization's competitive strategy and its likelihood of success.

A motorcycle traveling at 36 m/s slams on the brakes to avoid an accident. The motorcycle skids 23m before stoping. What is the
ValentinkaMS [3465]
Since the motorcycle was at a speed of 36 m/s prior to braking, that marks the initial velocity.
u = 36 {ms}^{ - 1}
The motorcycle skidded 23m before coming to a full stop, indicating that
s = 23m
As it has ceased motion, the final velocity is zero.

v = 0{ms}^{ - 1}
We can apply the 'suvat' formula relevant to linear motion.

{v}^{2} = {u}^{2} + 2as
Substituting the aforementioned values allows us to find,

{0}^{2} = {36}^{2} + 2a(23)


0 = 1296+ 46a
46a = - 1296
a = - 28.2 {ms}^{ - 2}


We can apply the formula
v = u + at
to calculate the time required for the motorcycle to stop.

0 = 36 + - 28.2t
- 36 = - 28.2t
t = 1.3s

Scientists often use models to study the movement of continents. Why might scientists use a model to show this movement? A. Extr
Maru [3345]
For many years, paleontologists have maintained that the extinction of dinosaurs was primarily due to climate changes linked to gradual shifts in the arrangement of continents and oceans as a consequence of plate tectonics. Throughout the Cretaceous period, which marked the peak of dinosaur existence, extensive shallow seas intermittently covered vast portions of land. Evidence from various geological sources, such as chemical clues found in ocean floor sediments, suggests that the climate during the Late Cretaceous was warmer and more stable compared to the present. The daytime temperatures were moderate, as were the nighttime chills, with summers and winters being neither excessively hot nor incredibly cold. It is likely that the shallow continental seas helped regulate the air temperature nearby, maintaining a consistent climate.
