Answer:

Electromagnetic forces are stronger than gravitational forces.

Explanation:

Electromagnetic and gravitational forces both are fundamental forces present in nature. The force that exists between the charged particles are electromagnetic forces while the force that exists between two objects in the universe is called gravitational force.

The one of the difference between these two forces is that the gravitational force is always attractive while the electromagnetic force can be attractive or repulsive.

Electromagnetic forces are stronger than gravitational forces. It is approximate 10³⁹ times stronger than gravitational force. Hence, the correct option is (b).

When using a calorimeter, the initial temperature of a metal is 70.4C. The initial temperature of the water is 23.6C. At the end

Sunny_sXe [5.5K]

1) 29.8 C

At the beginning, the metal is at higher temperature (70.4 C) while the water is at lower temperature (23.6 C). When they are put in contact, the metal transfers heat to the water, until they reach thermal equilibrium: at thermal equilibrium the two objects (the metal and the water have same temperature). Therefore, since the temperature of the water at thermal equilibrium is 29.8 C, the final temperature of the metal must be the same (29.8 C).

2) 6.2 C

The temperature change of the water is given by the difference between its final temperature and its initial temperature:

$\Delta T = T_f - T_i$

where

$T_f = 29.8 C\\T_i = 23.6 C$

Substituting into the formula,

$\Delta T=29.8 C-23.6 C=6.2 C$

And the positive sign means that the temperature of the water has increased.

3) -40.6 C

The temperature change of the metal is given by the difference between its final temperature and its initial temperature:

$\Delta T = T_f - T_i$

where

$T_f = 29.8 C\\T_i = 70.4 C$

Substituting into the formula,

$\Delta T=29.8 C-70.4 C=-40.6 C$

And the negative sign means the temperature of the metal has decreased.

Given an explicit organization culture, organization members tend to make decisions that are consistent with the values embedded

Andrew [12]

Answer:

True.

Explanation:

The explicit culture include attitudes, practices, signs and legends of a society are basic features of culture. This includes the way people look, the kind of food they eat, music, dance, the amazing and/or ugly things they consider. SO, in an explicit organization culture organization members tend to make decisions that are consistent with the values embedded in that culture.

A suitcase has mass of 4.1 kg and sits on a counter 1.8 m high in the airport. How much gravitational potential energy does it h

velikii [3]

Answer:

72.324 J

Explanation:

Formula for gravitational potential energy is given by;

GPE = mgh.

Where;

m = mass

g = acceleration due to gravity

h = height

We are given;

m = 4.1 kg

h = 1.8 m

Thus;

GPE = 4.1 × 9.8 × 1.8 = 72.324 J
