Answer:
Coccus
Explanation:
Berry shaped bacterium. Streptococci. Berry shaped bacteria occurring in twisted chains
Explanation:
Power = Work done ÷ Time
P = 28056 ÷ 45 Watt
<u>P</u><u> </u><u>=</u><u> </u><u>6</u><u>2</u><u>3</u><u>.</u><u>4</u><u>6</u><u> </u><u>Watt</u>
In order to calculate the weight, we may simply use:
W = mg
W = 30 * 9.81
W = 294.3 N
The sum of the reaction force and the upward component of child pulling will be equal to total downward force. The force acting downwards is the weight. Therefore:
R + 12sin(45) = 294.3
R = 285.82 N
The acceleration can be found using the resultant force and the mass of the sled. The resultant force is:
F(r) = pulling force + pushing force - friction
F(r) = 12cos(45) + 8 - 5
F(r) = 11.48 N
a = F/m
a = 11.48 / 30
a = 0.38 m/s²
