Formerly, when scientists wanted to test substances, such as blood, they had to manually pipette each substance into individual

test tubes or plate wells.
Today, there are machines available that can pipette many substances simultaneously. So, a task that used to take hours can now be performed in minutes. This machine is an example of a technology that can help scientists

A.

collect samples.

B.

communicate information.

C.

perform computations.

D.

store data.

Answer:

A.

collect samples.

Explanation:

The main goal of science is to gain knowledge about the natural world, but this goal is nearly impossible to achieve without technology.

Technologies are products or processes that are created to solve a problem and/or take care of a human need. Technology is often used in science to collect samples, make measurements, collect and store data, analyze data through computations and graphing, and access remote locations, such as outer space.

You whirl a stone in a horizontal circle in such a way that the stone is in uniform circular motion. Which of the following is t
horsena [70]

a. The direction of the stone's velocity changes as it moves around the circle.

b. The magnitude of the stone's velocity does not change.

d. The change in direction of the stone's motion is due to the centripetal force acting on the stone.

Above given are true for the given situation.

<u>Answer:</u> Option A, B and D

<u>Explanation:</u>

Circular motion may be characterized as the moving of an objects along the diameter of the circle or any circular direction. It may be standardized and non-uniform based on whether or not the rate of rotation is unchanged.

The velocity, a vector quantity is constant in a uniform circle motion speed is constant as its direction continues to change. Centripetal force works inward toward the core to counterbalance the centrifugal force from the center moving outward.

Consider a simple parallel-plate capacitor whose plates are given equal and opposite charges and are separated by a distance d.
Aleksandr-060686 [28]

Answer:

c. Smaller than.

Explanation:

The energy stored in a capacitor is given as

E = 1/2CV²...................... Equation 1

Where E = Energy stored in a capacitor, C = capacitance of the capacitor, V = Voltage.

Also,

C = εA/d ......................Equation 2

Where ε = permitivity of the material, A = cross-sectional area of the plate, d = distance of separation of the plate.

substitute equation 2 into equation 1

E = 1/2εAV²/d ................. Equation 3

From equation 3 above,

The energy stored in a capacitor is inversely proportional to the distance of separation between the plates.

Hence when the plate is pulled apart by a distance D (D>d) The energy stored in the capacitor will be smaller.

The right option is c. Smaller than.
