The density of lead is 11.3 g/cm 3. What mass of lead is required to make a 1 cm 3 fishing sinker?

Aliun [14]

Answer:

11.3 g

Explanation:

given,

density of the lead = 11.3 g/cm³

volume = 1 cm³

mass of the lead = ?

we know,

$density=\dfrac{mass}{volume}$

mass = volume x density

mass = 1 x 11.3

mass = 11.3 g

hence, the mass of the lead is equal to 11.3 g

The weight of an object is the product of its mass, mmm, and the acceleration of gravity, ggg (where g=9.8 m/s2g=9.8 m/s2). If a

Andre45 [30]

Answer:

Weight of the object will be 98 N

Explanation:

We have given mass of the object m = 10 kg

Acceleration due to gravity $g=9.8m/sec^2$

We have to find the weight of the object

Weight of the object is dependent on mass and acceleration due to gravity, it is the product of mass and acceleration due to gravity

So weight of the object W = mass × acceleration due to gravity

So $W=10\times 9.8=98N$

So weight of the object will be 98 N

Which option below correctly compares the average annual dose of background radiation to the dose liked to an increased cancer r

julia-pushkina [17]

The answer for this question would be choice "<span>B. The average annual dose of background radiation is 250 times smaller than the dose linked to increased cancer risk."

You only have to compare 4.0 x 10^-4 and 1.0 x 10^-1. And if you can observe carefully, when you try to multiply the average annual dose of background radiation by 250, you would get 0.1 which is equivalent to the amount of annual dose linked to increased cancer risk. Therefore, the answer is B.</span>
