If the mass of an object doubles, the weight of the object also doubles

If the mass of an object halves, the weight of the object also halves

Explanation:

The mass of an object is an intrinsec property of the object that gives a measure of the "amount of matter" in the object. Mass is indipendent from the location of the object.

On the contrary, weight gives a measure of the force of gravitational attraction felt by the object in a gravitational field. Weight is dependent on the location.

The mass and the weight of an object are related by the following equation:

$W=mg$

where:

W is the weight of the object

m is its mass

g is the acceleration of gravity

We see from the formula that the weight of an object is directly proportional to its mass. This means the following:

If the mass of an object doubles, the weight of the object also doubles
If the mass of an object halves, the weight of the object also halves

The acceleration due to gravity on Jupiter is 2.5 times what it is here on earth. An object weighing 347.9 N here on earth will

inessss [21]

Answer: weight on Jupiter = 869.75 N

mass on Earth = mass on Jupiter = 35.5 Kg

Explanation:

W = mg

W = weight

m = mass

g = gravitational acceleration [ on the Earth, g₁ = 9,8 N/kg ]

On the Earth,

G₁ = m x g₁ = 347,9 N

On the Jupiter,

G₂ = mg₂

mass on the Earth = mass on the Jupiter !

m = G₁ : g = 347.9 N : 9,8 N/kg = 35.5 kg

G2 : G1 = 2.5

G₂ = 2,5 G₁ = 2,5 x 347.9 N = 869,75 N

How much current is drawn by a television with a resistance of 30 ω that is connected across a potential difference of 120v?

melomori [17]

By using the Ohms law, we can calculate the current.

Ohms law,

$\frac{V}{I} = R$

Here, V is potential difference, and R is the resistance.

Given, $V=120 V$ and $R = 30 ohm$ .

Therefore, putting the given values in above relation , we get

$\frac{120V}{I} = 30 ohm$

or $I=\frac{120}{30} = 4 A$

Thus, the current is drawn by a television 4 Ampere

g A bowling ball with a mass of 3.86 kg and a radius of 0.161 m starts from rest at a height of 2.5 m and rolls down a 48.4 o sl

Fynjy0 [20]

Answer:

$v=1.5m/s$

Explanation:

The gravitational potential energy gets transformed into translational and rotational kinetic energy, so we can write $mgh=\frac{mv^2}{2}+\frac{I\omega^2}{2}$ . Since $v=r\omega$ (the ball rolls without slipping) and for a solid sphere $I=\frac{2mr^2}{5}$ , we have:

$mgh=\frac{mv^2}{2}+\frac{2mr^2\omega^2}{2*5}=\frac{mv^2}{2}+\frac{mv^2}{5}=\frac{7mv^2}{10}$

So our translational speed will be:

$v=\sqrt{\frac{10gh}{7}}=\sqrt{\frac{10(9.8m/s^2)(0.161m)}{7}}=1.5m/s$

The tendency for an object to sink or float has to do with the object's density.<br> True<br> False

Stella [2.4K]

Answer:

TRUE

Explanation:

BECAUSE AN OBJECTS DENSITY SHOWS HOW MUCH WEIGHT IS PER CUBIC UNIT. LIKE SAD HAS MORE DENSITY THAN WATER SO IT SINKS WHILE WOOD HAS LESS DENSITY THAN WATER SO IT FLOATS
