Answer:

The answer is below

Explanation:

The acceleration of a ball rolling down an inclined plane would be greater than that of the acceleration of a ball rolling up if acted upon by a force of equal magnitude. For a ball rolling down an inclined plane, the acceleration due to gravity (gsinθ) acts in the direction of motion of the ball thereby leading to an increase in the acceleration of the ball; while for a balling rolling upwards, the acceleration due to gravity acts in the direction opposite to the motion of the ball thereby leading to a decrease in the acceleration of the ball.

Answer:

$141.30grams$

Explanation:

First, denote our known values;

$J=1.3N-s(+,east)\\u=-3.8ms^-^1(-,west)\\v=5.4ms^-^1(+,east)\\m=?$

Mass is impulse divided by change in velocity:

$m=\frac{J}{v-u}\\=\frac{1.3}{5.4--3.8}\\\\=\frac{1.3}{9.2}\\=0.1413Kgs$

Hence, the mass of the ball is 141.30grams

Which of the following statements about the impact of biotechnology on the environment is not true?

Vladimir79 [104]

E) Biotechnology use can lead to an increase in soil erosion and pollution runoff through decreased pesticide use.

Explanation:

Biotechnology use cannot lead to an increase in soil erosion and pollution runoff through decreased pesticide use.

There is no relationship between biotechnology use and increase soil erosion and pollution run off.

Biotechnology involves the application of technology based on living things.
