What happens to the value of y when the value of x changes in y equals 4x?
y = 100 - 4x ( a ) Find the value of y when x = 20.
Approximation of sin x by x?
the value of sin(x) lies between -1 to +1. the approx value of sin(x)/x = 1 when x tends to 0 & sin(x)/x = 0 when x tends to infinity.
Find the value of 2x² when x equals 3?
18
What is the limit of sin x?
Sin(x) has a maximum value of +1 and a minimum value of -1.
X plus x plus x equals 180 then what is the value of x?
60
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
What is the ratio of force to acceleration?
The ratio is the M/cos(x). where M is the mass on which the force is acting and x is the angle between the direction of the force and the direction of the acceleration.
Where does the direction of the acceleration arrow point in?
The direction of the acceleration arrow points in the direction of the acceleration vector, which indicates the rate of change of an object's velocity. If the arrow is pointing upwards, it means the acceleration is in the positive y-direction; if it's pointing left, it means the acceleration is in the negative x-direction, and so on.
When a cart is changing direction is it acceleration?
Yes, changing direction involves acceleration because acceleration is the rate of change of velocity. When an object changes direction, its velocity changes, which means it is experiencing acceleration.
Is acceleration due to change in direction?
Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.
A classmate in the physics state that the negative acceleration always mean that a moving object is decelerating is that true?
No, that statement is not entirely true. Negative acceleration means the velocity of the object is decreasing, which could be due to deceleration (slowing down) or changing direction. Positive acceleration means the velocity is increasing.
Which acceleration has larger magnitude?
The acceleration with the larger magnitude is the one with a greater numerical value, regardless of its direction. Acceleration is a vector quantity, meaning it has both magnitude and direction, but when comparing magnitudes, only the numerical values are considered.
What is the direction of instantaneous acceleration?
The direction of instantaneous acceleration is in the direction of the change in velocity at that moment. If the velocity is increasing, the acceleration is in the same direction as the velocity. If the velocity is decreasing, the acceleration is in the opposite direction of the velocity.
What shall you do when you find the value of driving force is negative?
The acceleration is in the direction of the positive force so you will have deceleration in the direction of the negative force.
When is the acceleration of a body is positive?
A body's acceleration is positive when its velocity is increasing over time. This can happen when the body is speeding up in the same direction as its velocity, or when it is slowing down in the opposite direction of its velocity. Both scenarios result in a positive acceleration value.
Is Centripetal acceleration a vector?
Um, well... it can be represented by a vector.Just like anything else that has both a direction and a value.The mere numerical value of an acceleration is not a vector,since it's just a value without a direction.
How do you work out the deceleration?
Deceleration can be calculated by dividing the change in velocity by the time taken for that change to occur. The formula for deceleration is: deceleration = (final velocity - initial velocity) / time. Make sure to use consistent units for velocity and time when performing the calculation.
