Which of these experiments tests a chemical property of an object??
Ilia_Sergeevich [38]
<span>B. shining a bright light on the objects and testing for decomposition </span> <span>      

In explanation, chemical property is a characteristic of a certain substance came from an outcome due to chemical change or reaction. In the situation above, more specifically toxicity is involved in the chemical property/change. Hence, when the object is tested for decomposition. Like for an example of decomposition simply in metals, rusting. Rusting a process of degeneration of metals. Here it works the same. Toxicity is how much damage did a certain entity do to the object. </span>

If a negatively charged rod is held near a neutral metal ball, the ball is attracted to the rod. This happens:_______
qaws [65]

Answer:

<em>c. because the rod polarizes the metal.</em>

Explanation:

Bringing the negatively charged rod close to the neutral metal ball causes the neutral metal ball to be polarized with induced positive charge on it. The polarizing of the formally neutral metal ball is due to the negative charge on the metal rod (bodies induce a charge opposite of their own charge on a nearby neutral body). The ball and rod then attract themselves because bodies with opposite charges attract each other, unlike bodies with same charges that repel each other.

If a person uses about 4 calories to fuel a minute of walking, and it takes about 20 minutes to walk a mile, approximately how m
Lemur [1.5K]

Answer:

43.75 miles must a person walk to utilize the energy in (“burn”) a pound of fat.

Explanation:

3,500 calories are present in 1 pound of the fat.

Thus, given that:

<u>4 calories are burnt in 1 minute of walking.</u>

So,

1 calories are burnt in 1/4 minute of walking.

Or,

<u>1 calories are burnt in 0.25 minute of walking.</u>

Thus,

<u>3500 calories are burnt in 0.25*3500 minutes of walking</u>

Minutes of walking needed to burn 3500 calories = 875 minutes.

Also, given that:

<u>20 minutes of walking covers 1 mile.</u>

<u>1 minute of walking covers 1/20 mile.</u>

So,

<u>875 minutes of walking covers (1/20)*875 mile.</u>

<u>43.75 miles must a person walk to utilize the energy in (“burn”) a pound of fat.</u>

URGENT I WILL GIVE BRAINLIEST
Reil [10]

Weight : It is the gravitational attraction force on an object near its surface.

It is always measured in the unit of Newton(N)

it is given by the product of mass and acceleration due to gravity

W = mg

here we know that mass of the pig is m = 140 kg

also we know that acceleration due to gravity near the surface of earth is approximately g = 9.8 m/s/s

so here we know by above formula

W = (140 kg)(9.8 m/s^2)

W = 1372 N

so correct answer will be

<em>D. 1372 N</em>
