Answer:
(a) It will take 12.82 sec to come into rest
(b) After calculation distance is 737.15 m which is less than 800 m so jet can land on the island
Explanation:
(a) When the jet lands at the ground its velocity is 115 m/sec
So initial velocity u = 0 m/sec
Finally jet will stop so its final velocity will be zero v = 0 m/sec
Maximum acceleration
So minimum time,
So
t = 12.82 sec
(b) Average speed
Distance traveled in 12.82 sec =
As this distance is less than 800 m so jet can land on the island
sensory nerve - spinal cord - motor nerve - effector work together to cause the reflex to lift the foot.
<h3>What role does the spinal cord play?</h3>
The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lower back together. Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
<h3>What occurs if the spinal cord is hurt?</h3>
Nerve function is lost beneath the site of damage. A spinal cord damage higher up can paralyze the majority of the body and all limbs (called tetraplegia or quadriplegia). Legs and lower body paralysis may result from a lower spinal cord injury (called paraplegia).

#SPJ4
Explanation:
Given parameters:
Jermaine runs exactly 2 laps around a 400m track
Start time = 3:02:00PM
End time = 3:04:45PM
Unknown:
Distance traveled = ?
Speed = ?
Displacement = ?
Velocity = ?
Solution:
To solve this problem, we need to find the distance and time first;
Distance = 2 x 400 = 800m
Time taken = 3:04:45PM - 3:02:00PM = 165s
Speed = = = 4.85m/s
The velocity of the body is 0m/s and so is the displacement.
This is because the starting and finishing position of the Jermaine is the same.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We calculate as follows:
</span>2.0x10^22 molecules H2O ( 1 mol / 6.022 x 10^23 molecules ) = 0.0332 moles H2O
Hope this answers the question. Have a nice day.
Answer:
decrease
Explanation:
If the two charged ball attracts each other, it means the charge on both the balls are opposite in nature.
As, we insert a glass slab, it means a dielectric is inserted in between the charges. The force between them is reduced.
