Answer: Vacuoles

Explanation: Vacuoles are large bubble found in the cells. They are found both in plants and animals.

The vacuoles found in the animal cells are comparatively smaller as compared to plants.

They store food or any other variety of nutrients that the cell might need in order to survive. Those substances can be carbohydrates, protein, salts and proteins.

They can also store the waste materials of the cell.

In a football game the running back is running up the field. He starts from rest and runs 4 seconds with an acceleration of 1.3m

Amiraneli [1.4K]

Answer:

3.38m

Explanation:

Given parameters:

Time = 4s

Acceleration = 1.3m/s²

Unknown:

Magnitude of the displacement = ?

Solution:

The body starts at rest and the initial velocity is 0m/s. To solve this problem, we have to use the expression below;

S = Ut + $\frac{1}{2}$ at²

S = displacement

t is the time

a is the acceleration

U is the initial velocity

V is the final velocity

Insert the parameters and solve;

S = (0 x 4) + $\frac{1}{2}$ x 1.3² x 4 = 3.38m

Does the dependenceof the orbital energy on nmake sense in terms of the total number of nodes in each type of orbital?.

erma4kov [3.2K]

Answer:The 2s orbital different than the 1s orbital because the 2s orbital extends farther from the nucleus than the 1s.

As we move away from the nucleus, the values of the principal quantum number (n) continues to increase.

As the principal quantum number (n) increases, the orbital becomes farther away from the nucleus.

The higher energy orbital are always larger than the orbitals closer to the nucleus.

Hence, the 2s orbital different than the 1s orbital because the 2s orbital extends farther from the nucleus than the 1s.

7. An auto's velocity increases uniformly from 3m/s to 25m/s while

AnnyKZ [126]

Answer:

3.422 m/s^2

Explanation:

A useful relation is ...

v2^2 -v1^2 = 2ad

(25 m/s)^2 -(3 m/s)^2 = 2a(90 m)

(616 m^2/s^2)/(180 m) = a ≈ 3.422 m/s^2

The acceleration is about 3.422 m/s^2.

the length of the sliding rod is 0.1 m and its speed is 2.0 m/ and b is 0.60 t. a) if the total resistance of the loop is 0.05 ,

Aleks [24]

The induced current produced due to moving sliding rod having resistance 0.05 is 2.4 A.

Induced current:

Any change in the magnetic field associated with a coil of wire will cause an emf to be induced in the coil. This emf is called induced emf and if the conductor circuit is closed, current will also circulate through the circuit. This current is called induced current.

Given, length of sliding rod, l= 0.1 m

Magnetic field = 0.60T

Velocity = 2m/s

Resistance of the loop = 0.05

Emf Induced = Blv

induced current = Blv/R

$i = \frac{0.6 \times 0.1 \times 2}{0.05}$

$i = \frac{0.12}{0.05}$

$i = 2.4$

so, the current produced in sliding rod moving withspeed of 2m/s in magnetic field 0.6 T and having resistance of loop 0.05, is 2.4 A
