Answer:
A
Explanation:
Ethanol fermentation causes bread dough to rise. Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it to a foam.
Explanation:
K.E. of marble 1 = (1/2) × 0.2 × (22/0.8) ^2
= 0.1 × 756.25
= 75.625
K.E. of marble 2 = (1/2) × 1.2 × (26/0.8)^2
= 0.6 × 1056.25
= 633.75
Answer:
<em>C</em>
Explanation:
<em>Tennis would belong to net wall games .</em>
Well for example if you’re throwing a ball The force that moves the ball "up"
must overcome (be larger than) the downward force of the ball's weight.
Once the upward "force of the throw" overcomes the weight, it must then accelerate the ball upward, in order to give an initial upward speed.
Newton's formula: Fnet = ma
indicates that the acceleration (a) will equal the *excess upward force* {once the weight force is cancelled} divided by the ball's mass.
so in summary:
Fnet in Newtons will be the child's UPward force minus the ball's weight.
