Answer:
Then the cell won't be able to function properly. With no nucleus the cell will lose control. It won't know what to do and there will be no cell division.
Explanation:
length of the grilling machine is 1.2 m
time taken to cook the burger is 2.7 min = 162 s
so the speed of the machine should be like this that if must have to cook till it cross the machine
now in one minute the total length of the machine that is covered is given by
now distance between the burgers is 15 cm
so total production rate will be
so it will produce 3 burger per minute
Answer:
140.04 m from the stop.
Explanation:
We can divide the motion in two parts:
First, we have an uniformly accelerated motion, using the following formula we calculate the distance traveled in this part:
In the second part, the car decelerates, but we don't know the value of this deceleration. We have to calculate the time spend in the first part, in order to know the time spend on second part:
Recall that total time is 15 s
Now, we calculate the deceleration:
Finally, we find the distance traveled in the second part. In this way, we can know how far does the car travel.
Answer:
<em>time = 6.9 s</em>
<em></em>
Explanation:
velocity of the plane v = 22.7 m/s
acceleration of the train a = -3.3 m/s^2
it finally comes to res, final velocity u = 0 m/s
time t = ?
using the equation
v = u + at
substituting, we have
0 = 22.7 + (-3.3)t
0 = 22.7 - 3.3t
3.3t = 22.7
t = 22.7/3.3 = <em>6.9 s</em>
