Answer:
The time it will take for the driver to reach Ottawa is 3 hours 32 minutes and 45 seconds
Explanation:
The given parameters are;
Speed of the car = 120 km/h
Distance from Toronto to Ottawa = 425.5 km
The formula for speed is given as follows;
Speed = Distance/Time
Therefore, to find the time duration it takes from Toronto to Ottawa, we have;
Time duration = Distance from Toronto to Ottawa/(Speed of the car)
The time duration = 425.5/120 = 3.54583 hours = 212.75 min = 12765 seconds
The time it takes from Toronto to Ottawa while driving at 425.5 km/h = 12765 seconds.
In atmospheric science, surface pressure<span> is the atmospheric </span>pressure<span> at a location on Earth's </span>surface<span>. It is directly proportional to the mass of air over that location. For numerical reasons, atmospheric models such as general circulation models (GCMs) usually predict the nondimensional logarithm of </span>surface pressure<span>.
The answer is decrease more slowly

Answer:
40m approximately
Explanation:
Given
Force =377N
Mass =86.5kg
Velocity =13.2m/s
Required
Radius of the track
The expression for the centripetal force acting on the cyclist is
F=mv²/r
Make r subject of the formula
r= mv²/F
Substitute
r=86.5*13.2²/377
r= 15,071.76/377
r=39.97
r=40m approximately
