Answer:

D. systems, termed as "organ system".

Explanation:

The organ system is a system that consists of a group of organs that work together to ensure that the organism continues to survive.

Tissues are next in creating the specific organs, and are generally classified depending on the organ it is part of. Note that not all tissues are the same.

Cells are "the smallest", and groups of cells create tissues.

Nerves are part of the Nervous system, which helps provide sensory to the body to help react when the body comes into contact with something that may hurt body parts.

Suppose you exert a force of 180 N tangential to a 0.280-m-radius 75.0-kg grindstone (a solid disk). What is the angular acceler

Lina20 [59]

Explanation:

It is given that,

Force on grindstone, F = 180 N

Radius of grindstone, r = 0.28 m

Mass of grindstone, m = 75 kg

We need to find the angular acceleration of the grindstone. In rotational motion, the relation between the torque and angular acceleration is given by :

$\tau=I\times \alpha$

$\alpha=\dfrac{\tau}{I}$

I is the moment of inertia of solid disk, $I=\dfrac{1}{2}mr^2$

$\tau$ is the torque exerted, $\tau=F\times r$

$\alpha=\dfrac{F\times r}{\dfrac{1}{2}mr^2}$

$\alpha=\dfrac{2F}{mr}$

$\alpha=\dfrac{2\times 180\ N}{75\ kg\times 0.28\ m}$

$\alpha =17.14\ rad/s^2$

So, the angular acceleration of the disk is $17.14\ rad/s^2$ . Hence, this is the required solution.

What adaptation in frogs enables them to swim

Flauer [41]

Answer:

Most of the frogs have webbed feet which helps them swim. The thin skin between the toes helps them to push through the water. The frog's feet is webbed ,So they can easily swim.. The skin between toes are flexible soo they can freely push and pull it

State the ohm's law in words

Anton [14]

Explanation:

Ohm's law states that the voltage or potential difference between two points is directly proportional to the current or electricity passing through the resistance, and directly proportional to the resistance of the circuit. The formula for Ohm's law is V=IR.
