Explanation:
The time for the ball to reach the bottom of the ramp is 5 seconds. Using this time value, the acceleration, and the initial velocity, you can calculate the length of the ramp, which is found to be 125 cm.
The question involves the physics principles of kinematics, specifically the concept of acceleration. Given that the initial velocity is 0 cm/s, the final velocity is 50 cm/s, and the acceleration is 10 cm/s^2, you can find the time it took for the ball to reach the bottom using the formula vf=vi+at (Final velocity = initial velocity + acceleration * time). Substituting the given values, you get the equation 50cm/s = 0cm/s + 10cm/s^2 * time, simplifying which gives time = 5 seconds.
To find the length of the ramp, you can use another kinematic equation, d = vit + 0.5at^2 (Distance = initial velocity * time + 0.5 * acceleration * time^2). Substituting the values we know, (initial velocity = 0, acceleration = 10 cm/s^2, time = 5 s), the equation simplifies to d = 0*5 + 0.5*10*5^2 = 0 + 0.5*10*25 = 125 cm. Therefore, the length of the incline or ramp is 125 cm.

B)terrestrial planets and asteroids
C)dwarf planets like Pluto
False
False
If the object weighs more than the buoyant force then the object will sink.
This is because the buoyant force "pushes" the object upwards and the weight of the object "pushes" the object downwards. Since the force downwards is greater than the force upwards the item will sink, so this statement is False.

The mass of solid formed is 2.654 g
calculation
step 1: write the balanced molecular equation
=2AgNO3(aq) + k2CrO4(aq)→ Ag2CrO4(s) + 2 KNO3(aq)
step 2: calculate the moles of K2CrO4
moles = molarity x volume in liters
molarity = 0.200 M = 0.200 mol/L
volume = 40 .0 ml in liters = 40/1000 = 0.04 liters
moles is = 0.200 mol/l x0.04 L =0.008 moles
Step 3: use the mole ratio to determine the moles of solid formed( Ag2CrO4)
K2CrO4 :Ag2CrO4 is 1:1 therefore the moles of Ag2CrO4 is also
0.008 moles
step 4: calculate the mass of Ag2CrO4
mass = moles x molar mass
from periodic table the molar mass of Ag2Cro4
=(107.87 x2) + 52 +(16 x4) =331.74 g/mol
mass = 0.008 moles x 331.74 = 2.654 g
