Answer:

5.8 kg*m/s

Explanation:

p = mv

momentum = mass times velocity

momentum =  0.145 kg times 40.0 m/s

momentum =  0.145* 40.0

momentum = 5.8 kg*m/s

Given what we know, we can confirm that due to its relatively low image quality, any memory card with at least one MB will be sufficient to hold the 120 images taken.

The photos are taken at 8 megapixels, with each one occupying 14 bits of information. A megabit consists of one million bits of potential storage. Therefore, the 120 pictures will occupy roughly 1% of the available storage of a 1 MB memory card.

Therefore, we can confirm that due to its relatively low image quality, any memory card with at least one MB will be sufficient to hold the 120 images taken.

Answer:

[tex]\huge\boxed{\sf x = 18\°}[/tex]

Explanation:

If ∠ABC and ∠DEF are complementary angles, this means they add up to 90 degrees.

So,

∠ABC + ∠DEF = 90°

72 + x = 90

Subtract 72 to both sides

x = 90 - 72

x = 18°

The highest frequency sound to which the machine can be adjusted is :

Given data :

Pressure = 10 Pa

Speed of sound = 344 m/s

Displacement altitude = 10⁻⁶ m

applying the formula below

Therefore :

f = ( Pmax * V ) / [tex]2\pi \beta A[/tex]

 = ( 10 * 344 ) / 2[tex]\pi[/tex] * 1.31 * 10⁵ * 10⁻⁶

Answer: Can't see clearly.

Explanation:

Answer:

wd = F * D

wd = 100 * 5

wd = 500

The work done on the box is 500 Joules.

When an object is moved over a distance by an external force, at least a portion of which is applied in the direction of the displacement, it is said to have done "work" in physics. By multiplying the length of the path by the component of the force acting along the path, work can be calculated if the force is constant.

As work is a scalar quantity, it can be defined only by magnitude, it has no direction. SI unit of work is Joule and CGS unit of work is erg.

Given parameters:

Mass of the box: m = 4 kg.

Force applied on the box: F = 100 N.

Displacement of the box: d = 5 meters.

Hence, the work done on the box is = applied force × displacement

= 100 N × 5 meters

= 500 Joules.

The acceleration produced will be one-half as much.

Acceleration is rate of change of velocity with time. Due to having both direction and magnitude, it is a vector quantity. SI unit of acceleration is meter/second² (m/s²).

From Newton's 2nd law of motion; it can be written that:

Force = mass × acceleration

acceleration = force/mass.

Now, according to the question, an unbalanced force of 2 newtons applied to a given mass produces an acceleration.

So, when  an unbalanced force of 1 newton is applied to the same mass, the force applied on the object becomes half.

Hence, from the equation, the acceleration produced will be one-half as much.
