According to Newton's second Law of motion, if the mass of an object is 10 kg and the force is 10 newtons, then the acceleration is 1m/s².
How to calculate acceleration?The acceleration of a moving body can be calculated by dividing the force of the body by its mass.
According to this question, the mass of an object is 10 kg and the force is 10 newtons, then the acceleration can be calculated as follows:
acceleration = 10N ÷ 10kg
acceleration = 1m/s²
Therefore, according to Newton's second Law of motion, if the mass of an object is 10 kg and the force is 10 newtons, then the acceleration is 1m/s².

A car is moving along a straight line op is shown below it moves from O to P in 8sec and return to p to q in 6sec. What is the average velocity and the speed of the car
Answer:
The answer would be A
Explanation:
A snail is traveling along a straight path. The snail’s velocity can be modeled by
The acceleration of the snail will be 7/13 m/sec². The acceleration is found as the rate of change of the velocity.
What is acceleration?The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.
The given data in the problem is;
v(t)=1.4ln(1’t²) inches per minute
0<t<15 minute
Acceleration is found as;
[tex]\rm v('t)=1.4 \times \frac{1}{1+t^2} (2t)[/tex]
Acceleration at t= 5 minute;
[tex]\rm v'(5)=\frac{1.4(2)(5)}{1+5^2} =\frac{14}{26} \\\\ v'=\frac{7}{13}[/tex]
Hence, the acceleration of the snail will be 7/13 inch per square minute.

Greta is on the chairlift going up the mountain when one of her skis falls off.
The ski has a mass of 5 kg and hits the snow below with a speed of 72 km/h.
How high is the chairlift above the snow when the ski falls off?
(Ignore air resistance.)
The height of the chairlift above the snow when the ski falls off is determined as 20.4 m.
Conservation of energy
The height of the chairlift is calculated from the principle of conservation of mechanical energy as shown below;
P.E = K.E
mgh = ¹/₂mv²
gh = ¹/₂v²
h = v²/2g
where;
v is speed of the ski when it hits the snow below = 72 km/h = 20 m/sg is acceleration due to gravityh = (20)²/(2 x 9.8)
h = 20.4 m
Thus, the height of the chairlift above the snow when the ski falls off is determined as 20.4 m.

3. why is the sum of the maximum voltages across each element in a series r l c circuit usually greater than the maximum applied voltage? doesn't that inequality violate kirchhoff's loop rule?
The sum of the maximum voltages across each element in a series RLC circuit is usually greater than the maximum applied voltage because voltages are added by vector addition.
What is the Kichoff's loop rule?Kirchhoff's loop rule states that the algebraic sum of potential differences, as well as the voltage supplied by the voltage sources and resistances, in any loop must be equal to zero.
In a series RLCcircuit, the voltages are not added by scalar addition but by vector addition.
Kirchhoff's loop rule is not violated since the voltages across different elements in the circuit are not at their maximum values.
Therefore, the sum of the maximum voltages across each element in a series RLC circuit is usually greater than the maximum applied voltage because voltages are added by vector addition.
