Answer is cell wall.
Cell wall is a rigid structure which can be seen around the
cell membrane of the plant cell. It supplies support and strength to the plant.
Plant grows towards the light. Hence, the cells in the plant
should have much strength to hold the plant without falling down. This strength is provided from the cell walls
of the plant cells.
Answer:
12.0 meters
Explanation:
Given:
v₀ = 0 m/s
a₁ = 0.281 m/s²
t₁ = 5.44 s
a₂ = 1.43 m/s²
t₂ = 2.42 s
Find: x
First, find the velocity reached at the end of the first acceleration.
v = at + v₀
v = (0.281 m/s²) (5.44 s) + 0 m/s
v = 1.53 m/s
Next, find the position reached at the end of the first acceleration.
x = x₀ + v₀ t + ½ at²
x = 0 m + (0 m/s) (5.44 s) + ½ (0.281 m/s²) (5.44 s)²
x = 4.16 m
Finally, find the position reached at the end of the second acceleration.
x = x₀ + v₀ t + ½ at²
x = 4.16 m + (1.53 m/s) (2.42 s) + ½ (1.43 m/s²) (2.42 s)²
x = 12.0 m
The initial momentum of the car is
(mass) x (speed) = 20,000 kg-m/s
"Impulse" is (force exerted) x (time the force lasts)
and it's equal to the change in momentum.
(Force) x (10 sec) = 20,000 kg-m/s
Divide each side by (10 sec) and you have
Force = (20,000 kg-m/s) / (10 sec)
= 2,000 kg-m/s² = 2,000 Newtons
An example of a high specific heat is water’s specific heat, which requires 4.184 joules of heat to increase the temperature of 1 gram of water 1 degree Celsius. Scientifically, water’s specific heat is written as: 1 calorie/gm °C = 4.186 J/gm °C.
Answer:
absorbs heat and its kinetic energy increases.
Explanation:
As we know that heat is defined as the change in the temperature as there is increase in the temperature change then the heat will increase or decrease with respect to increase or decrease in temperature change.
In the given, question temperature is changing from 20° to 50° which means there is increase in the temperature which results in the absorption of heat. And increase temperature will increase the average speed of the molecules which results in increase in kinetic energy.
