<span>Cells may appear inactive during this stage, but they are quite the opposite. This is the longest period of the complete cell cycle during which DNA replicates, the centrioles divide, and proteins are actively produced. </span>
Acceleration = (change in speed) / (time for the change)
Change in speed = (ending speed) - (starting speed)
Change in speed = (60 km/hr) - (50 km/hr) = 10 km/hr
Time for the change = 12 sec
Acceleration = (10 km/hr) / (12 sec)
Acceleration = 0.8333 km/hr-sec
Convert to a unit that we can understand:
Acceleration = (0.8333 km/hr-sec)x(1000 m/km)x(hr/3600sec)
Acceleration = (833.3 / 3600) (m-hr / hr-sec²)
Acceleration = (833.3 / 3600) (m/s²)
<em>Acceleration = 0.231 m/s² </em> or 0.833 km/hr-sec²
Answer:
The speed is 
Explanation:
From the question we are told that
The magnetic field is 
The electric field is 
Generally the speed of the electron is mathematically represented as
Substituting values
Answer:
Cp = 397 [J/kg*K]
Explanation:
By means of the energy equation for heat transfer in substances and objects, we can calculate the specific heat. In this way, we have the following equation.
where:
Dt = temperature change = 10 [K]
m = mass = 0.5 [kg]
Q = heat = 1985 [J]
Cp = specific heat [J/kg*K]
Now replacing:
![1985=0.5*C_{p}*10\\C_{p}=\frac{1985}{0.5*10}\\C_{p}=397[\frac{J}{kg*K} ]](https://tex.z-dn.net/?f=1985%3D0.5%2AC_%7Bp%7D%2A10%5C%5CC_%7Bp%7D%3D%5Cfrac%7B1985%7D%7B0.5%2A10%7D%5C%5CC_%7Bp%7D%3D397%5B%5Cfrac%7BJ%7D%7Bkg%2AK%7D%20%5D)
The resultant of the two forces, vertical ground reaction force and frictional force is 1907.8784 N.
<h3>What is triangle law of vectors?</h3>
When two vectors are represented by magnitude and direction, then its resultant is given by the closing side of the triangle.
Given the vertical ground reaction force N = 2000N and horizontal frictional force F = 600N, then the resultant will be
R = √[(2000)² + (600)²]
R = 1907.8784 N
Thus the resultant force is 1907.8784 N
