Recall that
It takes the car about 3.2 s to reduce its speed from 14.6 to 10.8 m/s, since
Next, recall that
Then the car undergoes a displacement of about 41 m, since
Answer:
490m
Explanation:
Given parameters:
Time taken = 10s
Unknown:
Depth of the well = ?
Solution:
To find the depth of the well, we apply the appropriate motion equation:
h = ut + 
gt²
h is the depth
u is the initial velocity
g is the acceleration due to gravity = 9.8m/s²
t is the time taken
Input the parameters and solve;
The ball was dropped from rest; u = 0
h = gt²
h = x 9.8 x 10² = 490m
Answer:
A) An information security plan
Explanation:
Information Security is the practice of preventing unauthorized access to an organization's information. This helps to protect sensitive business information and data base to be accessed by unauthorized parties.
Since the increase in the number of information threats encountered by Ski Resort is due to the implementation of a new software system, this means their has been a loophole in the course of implementing the software system that allows malignant access to the company's information.
Kenny, the chief information officer, needs to establish a plan that ensures that the company's information and database is secured from parties that are not authorized.
If the light is traveling straight up, then it hits the interface (surface
or boundary) between water and air perpendicularly (90° to the surface).
This direction is the direction of the 'normal' to the surface. So the
angle of incidence is zero, and that means the angle of refraction is
also zero. The light just keeps going in the same direction when it
emerges into the air, and is not bent.
However, its speed increases in air, and that means its wavelength
also becomes longer than it was in the water.
Answer:
Explanation:
The gravitational force between the earth and another body is F = -GM_em/r^2 r where G = 6.67 times 10^-11 Nm^2/kg^2 is the gravitational constant, M_e = 5.97 times 10^24 kg is the mass of the earth, m is the mass of the other body, and r is the position vector of the second body with respect to the centre of the earth.
