Answer:

Letter A

Explanation:

Thigmotropism is the movement as response to a physical stimulus, usually the contact with a solid object or surface. Climbing vines are the only example of this.

Blooming flowers are an inner response of the plant-

Bending toward the light responds to a different kind of stimulus, the light.

Leaf abscission is the consequence of maturity of the plant.

A 15.0-mW laser puts out a narrow beam 2.00 mm indiameter.

UkoKoshka [18]

Explanation:

It is known that formula for energy per unit area per unit time is as follows.

S = $\frac{P}{A}$

= $\frac{P}{\pi \times r^{2}} = \frac{4P}{\pi d^{2}}$

$c \epsilon_{o} E^{2} = \frac{4P}{\pi d^{2}}$

E = $\sqrt{\frac{4P}{\pi d^{2} c \epsilon_{o}}}$

Now, putting the values we will calculate the electric field as follows.

E = $\sqrt{\frac{4P}{\pi d^{2} c \epsilon_{o}}}$

= $\sqrt{\frac{4 \times 15 \times 10^{-3} W}{3.14 \times (2mm \times \frac{1m}{1000 mm})^{2} \times 3 \times 10^{8} \times 8.85 \times 10^{-12}}}$

= 1341.03 V/m

Now, we will calculate the average magnetic field as follows.

B = $\frac{E}{c}$

= $\frac{1341.03 V/m}{3 \times 10^{8} m/s}$

= $4.47 \times 10^{-6}$ T

= $4.47 \mu T$

Thus, we can conclude that the average (rms) value of the magnetic field is $4.47 \mu T$ .

If the same force is applied to an object with a large mass it will have a blank acceleration

kati45 [8]

Answer:

If the same force is applied to an object with a large mass it will have a <u>smaller (lesser) </u>acceleration

Explanation:

force and mass are inversely proportional. force and acceleration are directly proportional. which means greater mass have smaller acceleration and smaller mass has greater acceleration. this is due to newtons second law of motion.
