What do you mean? are there any answers or like things you have? like paper plate or microwave?

A microwave is the fastest way to heat up food. But it's not the healthiest way to eat food. It's better to heat up food in the oven. The microwave contains too much radiation. Hope this helps! =)

The force of gravity between two objects follows an----- square law with regard to the distance between them what word completes

skelet666 [1.2K]

Answer:

Inverse

Explanation:

The force of gravity between two objects follows an inverse square law with regard to the distance between them.

The inverse square law refers to any law that stipulates that a particular quantity varies inversely to the square of the distance to its source and according to the law of universal gravitation, the gravitational force of attraction between two objects is inversely proportional to the square of the distance separating the two objects. 

Hence, the law of universal gravitation obeys the inverse square law.

The weight y of a fiddler crab is directly proportional to the 1.25 power of the weight x of its claws. A crab with a body weigh

frez [133]

Answer:

The weight of body is 1.3040 gram.

Explanation:

Given that,

The weight y of a fiddler crab is directly proportional to the 1.25 power of the weight x of its claws.

Suppose a crab with a body weight of 1.8 gram has claws weighing 1.1 gram.

Estimate the weight of a fiddler crab with claws weighing 0.85 gram.

Determine the weight of crab body

We need to calculate the value of proportional constant

$y\propto x^{1.25}$

$y=kx^{1.25}$

$k=\dfrac{y}{x^{1.25}}$

Put the value into the formula

$k=\dfrac{1.8}{1.1^{1.25}}$

$k=1.5978$

We need to calculate the crab weight

$y=kx^{1.25}$

Here, x = 0.85 g

Put the value into the formula

$y=1.5978\times(0.85)^{1.25}$

$y=1.3040\ gram$

Hence, The weight of body is 1.3040 gram.

A proton enters a magnetic field (B = 5.00 x 10^-2 T INTO THE PAGE) with

poizon [28]

Answer:

r = 1.16 m

Explanation:

It is given that,

Magnetic field, $B=5.6\times 10^6\ m/s$

Velocity of proton, $v=5.6\times 10^6\ m/s$

We need to find the radius (in m) of the circular path the particle will follow when it is travelling within the magnetic field. The radius followed by the proton is given by :

$r=\dfrac{mv}{qB}$

m is mass of proton, $m=1.67\times 10^{-27}\ kg$

So,

$r=\dfrac{1.67\times 10^{-27}\times 5.6\times 10^6}{1.6\times 10^{-19}\times 5\times 10^{-2}}\\\\r=1.16\ m$

So, the radius of circular path is 1.16 m.
