A fourth-grade teacher wants to ensure students understand the life cycle process of plants. The teacher decides to incorporate

Annette [7]

Answer:

There are several options that the teacher can use to incorporate the concept into students' understanding.

Explanation:

1. The students can draw all the plants that they know.

2. Children can be asked to bring the flowers to school so that they can identify the plants themselves.

3. The children can plat the flowers in makeshift pots and then take the best plants and transplant them in the garden or elsewhere.

4. The children can take occasional trips and observe and record any changes to the plants.

4. The teacher can ask the students to draw the flowers and emphasize on the productive parts like the stamens, leaves, pistils, stems.

(3.) A tourist travels 320 km in 3.6 h. What is her average speed for the trip?

solmaris [256]

Answer:

The average speed of the tourist is 88.89 km/h

Explanation:

Given;

distance of travel, d = 320 km

time of travel, t = 3.6 h

Average speed is given as;

average speed = distance / time

average speed = 320 km / 3.6 h

average speed = 88.89 km/ h

Therefore, the average speed of the tourist is 88.89 km/h

Quantity A of an ideal gas is at absolute temperature T, and a second quantity B of the same gas is at absolute temperature 2T.

Ira Lisetskai [31]

Answer: Yes both gases would have the same entropy.

Explanation:

The formula for the change in the entropy is as follows,

$\Delta S = \frac{Q}{T}$

Here, \Delta S is the change in the entropy, Q is the heat transfer and T is the temperature.

If the temperature of the system increases then there will be increase in the entropy as the randomness of the system increases.

In the given problem, if the both gases were initially at the same absolute temperature. Then there will be same entropy change in both gases.

Therefore, yes both gases would have the same entropy.

You want to estimate the diameter of a very small circular pinhole that you’ve made in a piece of aluminum foil. To do so, you s

mrs_skeptik [129]

Answer:C

Explanation:

Given

Wavelength of light $\lambda =632\ nm$

Screen is placed at a distance of $D=3.5\ m$

width of central maximum $w=15\ mm$

We know that width of central maximum is given by

$w=\frac{2.44\lambda D}{d}$

where d=diameter of hole

$d=\frac{2.44\lambda D}{w}$

$d=\frac{2.44\times 632\times 10^{-9}\times 3.5}{15\times 10^{-3}}$

$d=0.359\ mm$

$d=0.36\ mm$
