Answer:

The force exerted by the block on the floor is 38.4 Newtons

Explanation:

The given parameters are;

The area of the box in contact with the floor, A = 2.4 m²

The pressure exerted by the block on the floor, P = 16 N/m²

The force exerted by the box on the floor is given as follows;

Pressure, P = \dfrac{Force, F}{Area, A}

∴ F = P × A

From the question, P = 16 N/m², and A = 2.4 m²

∴ F = 16 N/m² × 2.4 m² = 38.4 N

The force exerted by the block on the floor, F = 38.4 N.

A small object with momentum 7.0 kg∙m/s approaches head-on a large object at rest. The small object bounces straight back with a
EastWind [94]

Answer:

The magnitude of the large object's momentum change is 3 kilogram-meters per second.

Explanation:

Under the assumption that no external forces are exerted on both the small object and the big object, whose situation is described by the Principle of Momentum Conservation:

p_{S,1}+p_{B,1} = p_{S,2}+p_{B,2} (1)

Where:

p_{S,1}, p_{S,2} - Initial and final momemtums of the small object, measured in kilogram-meters per second.

p_{B,1}, p_{B,2} - Initial and final momentums of the big object, measured in kilogram-meters per second.

If we know that p_{S,1} = 7\,\frac{kg\cdot m}{s}, p_{B,1} = 0\,\frac{kg\cdot m}{s} and p_{S, 2} = 4\,\frac{kg\cdot m}{s}, then the final momentum of the big object is:

7\,\frac{kg\cdot m}{s} + 0\,\frac{kg\cdot m}{s} = 4\,\frac{kg\cdot m}{s}+p_{B,2}

p_{B,2} = 3\,\frac{kg\cdot m}{s}

The magnitude of the large object's momentum change is:

p_{B,2}-p_{B,1} = 3\,\frac{kg\cdot m}{s}-0\,\frac{kg\cdot m}{s}

p_{B,2}-p_{B,1} = 3\,\frac{kg\cdot m}{s}

The magnitude of the large object's momentum change is 3 kilogram-meters per second.

A wave with a frequency of 14Hz has a wavelength of 3 meters. At what speed will this wave travel​
topjm [15]

Answer:

42 m/s

Explanation:

by definition of the velocity(speed) of a wave,

The velocity of light, v, is the product of its wavelength, λ , and its frequency, f.

V= fλ

frequency - number of occurances in a unit time

(check the graph)

velocity=frequency*wave.length\\=14Hz*3m\\=42 ms^{-1}
