Answer:
The percentage error e% = Δm/m 100
Explanation:
The absolute error is the assessment with which measurements are made, it is given by the minimum reading value of a given instrument.
The accepted value is the value measured in an instrument. Or the one calculated by an experiment.
The percentage error is the ratio of the absolute error between the value of the average per 100
e% = Δm/m 100
Displacement is defined as the net distance traveled through the entire trip. That is to say, if you compared where you are at the end of the walk to where you were at the start, the displacement is the distance between those two points.
Distance doesn't compare the two end points. It just counts the total distance you've walked throughout your trip.
Lisa walks once around the block. She starts and ends at the same place. Her displacement is therefore 0 m.
But she has walked 1 mile throughout the trip. Her distance walked is therefore 1 mile.
20 because if you go to 45 then scroll up it is at 20 degrees celcius
Answer:
2.5 m/s²
Explanation:
From the question
F = ma................... Equation 1
Where F = Tension, m = mass, a = acceleration of the car
make a the subject of the equation
a = F/m.................. Equation 2
Given: F = 1500 N, m = 600 kg
Substitute these values into equation 2
a = 1500/600
a = 2.5 m/s²
Hence the largest acceleration the rope can give to the car is 2.5 m/s²
Answer:
100km/hr
Explanation:
From the problem statement we know that distance of the trip is 115km
Expected time for the trip = 1.2hrs
→ If she spends the first half-hour going 90km/hr,
Here time = 0.5hr
speed = 90km/hr
The distance covered;
Distance covered = Speed x time
Distance covered = 90 x 0.5 = 45km
→The remaining distance will be:
Total distance - distance covered
115km - 45km = 70km
→ The remaining time;
1.2hr - 0.5hr = 0.7hr
Speed = 
Insert the parameters and solve;
Speed = 
= 100km/hr
For the remaining lap, the tourist must travel at a rate of 100km/hr to catch up.
