Read the following paragraphs, then answer the question on the right.

After handling contaminated dog food, fourteen people in nine states became ill from salmonella. According to the Centers for Disease Control and Prevention (CDC), the people who got sick had given that same contaminated dog food to their pets. At least five people were taken to a hospital, but the incident did not affect any of their dogs.

When people handle contaminated pet food and do not wash their hands well before eating or handling food, they can become ill with salmonella.

The plant that made the dog food was closed while the issue was investigated. The same plant had made food that was recalled by the pet food company four different times in the previous five months. Upon reopening the plant, the company issued a statement that it had taken action to fix the problems.

The cause of the illness was?
A.Not washing hands
B.Salmonella on dog food
C.Unknown

Waiting to see if the particles settle out of the mixture will be the next test to perform to determine the type of mixture.

This comprises of two or more substances which aren't chemically bonded together.

Suspension is a heterogeneous mixture that settle out of solution while colloid is a heterogeneous mixture that do not settle out of solution which is why option C was chosen.

Explanation:

Hey there!

According to the question;

Density of diamond (d) = 3.26g/cm³

And Volume (v) = 0.214 cm³

Mass(m) = ?

From the definition of density;

d = m/v

Or, 3.26 g/cm³ = m/(0.214 cm³)

or, 3.26 g/cm³ * 0.214 cm³ = m

Therefore, mass of the diamond is 0.69764 g.

Answer:

due to inertia of motion

Answer:

The distance travelled by the rock is 65m

The rock is thrown 15 m up from the edge of the cliff and it have to travel 15 m down to reach the cliff and go to bottom  of the cliff by 35 m. Thus, the total distance travelled by the rock is 65 m.

Distance is a physical quantity used to measure how far an object is travelling. It is a scalar quantity and is characterised by magnitude only. Distance travelled is sometimes substituted with displacement. Both have the units in cm, m, feet, kilometer etc.

Distance in physics is the product of the speed of a moving body and the time taken complete the travel.

Distance = speed × time.

It is given that, the rock is thrown straight up from the edge of a cliff and it reaches upto 15 m. Then it have to return back this 15 m down to reach the edge. From there it goes 35 m below.

Thus, total distance = 15 + 15 + 35 = 65 m.

Therefore, the total distance travelled by the rock is 65 m.

Answer:

force experienced by A and B are equal and opposite, that is total momentum before collision is equal to total momentum after collision if no external forces act on them which proves the principle of conservation of linear momentum.

Answer:

A. 1 J= 1 kg•m²/s²      :)

Explanation:

(a)

A = (75.0 cm) (cos(30°) i + sin(30°) j)

A = (75.0 cm) (√3/2 i + 1/2 j)

A ≈ (64.95 i + 37.5 j) cm

The x component is the coefficient of the i unit vector, while the y component is the coefficient of the j unit vector.

(b) "points along the negative axis" in other words means that B makes an angle of 180° with the positive x-axis in the counterclockwise direction. In particular this tells you that B is parallel to the x-axis, so its y component would be zero.

B = (25.0 cm) (cos(180°) i + sin(180°) j)

B = (25.0 cm) (-1 i + 0 j)

B = (-25.0 i) cm

(c) If the negative x-axis corresponds to 180°, then 45° below this would make an angle of 180° + 45° = 225° with the positive x-axis.

C = (40.0 cm) (cos(225°) i + sin(225°) j)

C = (40.0 cm) (-1/√2 i - 1/√2 j)

C ≈ (-28.28 i - 28.28 j) cm

(d) The sum A + B + C has components that are the sums of the components of each of A, B, and C.

A + B + C ≈ (11.67 i + 9.22 j) cm

(e) The magnitude of the vector sum is

||A + B + C|| = √((11.67 cm)² + (9.22 cm)²) ≈ 14.87 cm

(f) Since both components of the vector sum are positive, you know that it's a vector that terminates in the first quadrant of the x,y-plane, so it makes an angle with the positive x-axis of

arctan(9.22/11.67) ≈ 38.3°

Answer:

Range is 62.5 metres

Explanation:

Time of flight

[tex]t = \frac{2u \sin( \theta) }{g} [/tex]

for range, acceleration is zero

from second newton's equation:

[tex]S = ut + \frac{1}{2} {at}^{2} [/tex]

but a = 0:

let range be x:

[tex]x = ut \\ x = \frac{2 {u}^{2} \sin( \theta) }{g} \\ \\ x = \frac{ \{2 \times 25 {}^{2} \sin(30 \degree) \}}{10} \\ \\ x = 62.5 \: metres[/tex]

Explanation:

Explanation:

In Physics, many quanitties are the function of other quanitities.

For instance in kinematics, where the displacement (s), position (x), velocity (v) and time (t) of a particle are related.

Suppose the position of a particle can be descirbed as a function of time, i.e.

[tex]x=f(t)[/tex]

then since velocity is the rate of change of position, we write

[tex]v=\dfrac{d}{dt}f(t)=f'(t)[/tex]

which is the derivative of the poisiton/ time function.

On the other hand, the displacement of the particle is the sum of position changes over time, so the displacement can be defined by

[tex]s=\int^{t_1}_{t_0}f(t)dt[/tex]

which is the integration of postion/ time function.

Answer:

I (cylinder) = 1/2 M R^2

I (sphere) = 2/5 M R^2

The equation  of motion shows

I * alpha = M g R sin theta = const

An increase in the moment of inertia will result in a smaller acceleration

The cylinder will have the smallest forward velocity because it will arrive at the bottom after the sphere

Answer:

The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.

Explanation:

Its speed is zero at the beginning of the 3.25 s and 14 m/s at the end.

I'm thinking you probably wanted to find the car's acceleration.

Acceleration =(change in speed) / (time for the change).

Acceleration =(14m/s )/ (3.25s) .

Acceleration = 4.31m/s² .

The minimum depth of harbor of the oil tank is 2.22 m

The given parameters:

mass of the oil tanker, m = 40,000 tonnes

length of the tanker, l = 500 m

width of the tanker, w = 40 m

To find:

minimum depth of harbor

Note: The specific gravity of oil is approximately 0.9

          The density of water ([tex]\rho_w[/tex]) = 1000 kg/m³

Covert the given mass to kilogram

1 tonne = 1000 kg

40,000 tonnes = 40,000,000 kg

The density of the oil tanker is calculated as:

[tex]S.G = \frac{\rho_o}{\rho_w} \\\\\rho_o = S.G \times \rho_w\\\\\rho_o = 0.9 \times 1000\\\\\rho_o = 900 \ kg/m^3[/tex]

The volume of the oil tanker is calculated as:

[tex]Volume = \frac{mass}{density} \\\\Volume = \frac{40,000,000}{900} \\\\Volume = 44,444.44 \ m^3[/tex]

The minimum depth of harbor is calculated as:

[tex]height = \frac{volume}{Length \times width} \\\\height = \frac{44,444.44}{500\times 40} \\\\height = 2.22 \ m[/tex]

The minimum depth of harbor of the oil tank is 2.22 m
