The magnitude of the mower's acceleration of mass 36 kg is 1.15 m/s².
What is acceleration?Acceleration can be defined as the ratio of the change in velocity to the time of a body.
To calculate the magnitude of the mower's acceleration, we use the formula below.
Formula:
a = F/m................. Equation 1Where:
a = AccelerationF = Forcem = Mass of mowerFrom the question,
Given:
m = 36 kg41.5 NSubstitute these values into equation 1
a = 41.5/36a = 1.15 m/s²Hence, the acceleration of the mower is 1.15 m/s².

Given: g=10 m/s^2
A car moves a distance of 80 m during
a time interval of 10 s. The average
speed v_avg of this car is:
2 m/s
6 m/s
O 10 m/s
O 8 m/s
O 4 m/s
During a 10-second period, a car travels 80 meters. This car typically travels at a speed of 8 m/s.
An illustration of average velocity.For instance, if it takes a person 40 minutes to travel 20 miles north, 20 miles south, and finally 20 miles in between, their average speed is 40 miles divided by 40 minutes, or 1 mile per minute. Instead of distance, average velocity takes into account total displacement.
How is average velocity calculated?The total displacement must be divided by the total time elapsed in order to determine the average velocity.
average velocity= total displacement/ total time
avg velocity=80/10=8m/s

Why do some organisms make one type of protein for a feature while other organisms make two? Use the above words in your response.
Answer:
Genes provide instructions for making proteins but they do not build the proteins themselves. Why do some organisms make one type of protein for a feature and others make two? An organism has two copies of a gene for each feature; these can be the same version or different.
