    The percentage error in a measurement quantifies how much the measured value deviates from the true value, expressed as a percentage of the true value. The formula to calculate the percentage error is: Percentage Error=(∣True Value−Measured Value∣True Value)×100\text{Percentage Error} = \left( \frac{|\text{True Value} - \text{Measured Value}|}{\text{True Value}} ight) \times 100Percentage Error=(True Value∣True Value−Measured Value∣)×100 Given: True Value = 2.60 m Measured Value = 2.58 m Let's plug these values into the formula: Percentage Error=(∣2.60−2.58∣2.60)×100\text{Percentage Error} = \left( \frac{|2.60 - 2.58|}{2.60} ight) \times 100Percentage Error=(2.60∣2.60−2.58∣)×100 First, find the absolute difference:

    Determine the net displacement direction and distance: Moving 10 meters north is a positive displacement in the north direction. Moving 5 meters south is a negative displacement in the north direction. Calculate the net displacement: Net displacement = 10   meters north − 5   meters south = 5   meters north Net displacement=10meters north−5meters south=5meters north Magnitude of the displacement: The magnitude of the displacement is the absolute value of the net displacement. Magnitude of displacement = ∣ 5   meters ∣ = 5   meters Magnitude of displacement=∣5meters∣=5meters Thus, the magnitude of the displacement is 5 meters.

    @@syedsaliman2195 Acceleration is defined as the rate of change of velocity with respect to time. Velocity includes both speed and direction. If an object is moving at a constant speed, its speed does not change. However, for the object to have zero acceleration, its direction must also remain constant. Thus, when an object moves at a constant speed in a straight line (constant velocity), there is no change in its velocity, and hence its acceleration is zero. In summary: Constant speed implies no change in the magnitude of velocity. For acceleration to be zero, the direction must also be constant. Therefore, constant speed in a straight line results in zero acceleration.

    Yeah sure! To determine the acceleration of an object when a force is applied, you can use Newton's second law of motion, which is given by the formula: F=ma F=ma where: F F is the force applied, m m is the mass of the object, a a is the acceleration of the object. Given: Force F=10 N F=10N Mass m = 5 kg m=5kg We need to find the acceleration a a. Rearranging the formula to solve for a α: a=Fm α = m F Substituting the given values: a=10 N5 kg α = 5kg 10N a=2 m/s2 a=2m/s 2 So, the acceleration of the object is 2 m/s2 2m/s 2

    Some metals show brittle characteristics due to their slip systems. The more slip systems a metal has, the less brittle it is, because plastic deformation can occur along many of these slip systems.
