What temperature is considered unsafe working conditions? Failure to comply with these regulations can result in a lawsuit if workers become injured as a result of heat illness. While OSHA does not have specific regulations for indoor workplace temperatures, the agency recommends a temperature range between 68 and 76 degrees. What is the highest temperature […]
Why does intramolecular hydrogen bonding decreases boiling point?
Why does intramolecular hydrogen bonding decreases boiling point? Intramolecular hydrogen bonding occurs in two atoms of same molecule. It decreases the melting and boiling point because of chelation. Formation of chelation reduces the possibility of intermolecular hydrogen bonding and thus prevents association of the molecules which would have raised the melting or boiling point. Can […]
Which of the following graphs represents the motion of a particle moving with constant velocity?
Which of the following graphs represents the motion of a particle moving with constant velocity? Graph in option (d) shows an object moving at a constant velocity. Which of the following graphs represents constant speed of a body? A horizontal line on a speed-time graph represents a constant speed. A sloping line on a speed-time […]
What is surface energy formula?
Why is the solar calendar important?
Why is the solar calendar important? A solar calendar is a calendar whose dates indicate the season or almost equivalently the apparent position of the Sun relative to the stars. Why do we have 12 months instead of 13? Julius Caesar’s astronomers explained the need for 12 months in a year and the addition of […]
What happens when two water molecules collide?
What happens when two water molecules collide? What will happen when two water molecules bump into each other? When the oxygen atoms of 2 different water molecules come together, they repel. When the hydrogen atoms of 2 different water molecules come together, they repel. What does Frozen mean? frō’zən. Filters. The definition of frozen is […]
What are the 5 smart goals?
What are the 5 smart goals? By making sure the goals you set are aligned with the five SMART criteria (Specific, Measurable, Attainable, Relevant, and Time-Bound), you have an anchor on which to base all of your focus and decision-making. How do I write down my goals? In every self-help book you will ever read […]
Why work done has no direction?
Why work done has no direction? Work is nothing but the energy generated. Work has only a magnitude but no direction. The formula for work is written as a dot product of force and displacement. Therefore, work is a scalar quantity. What is present when work is done? Work is done when a force that […]
What will happen if animals disappear from Earth?
What will happen if animals disappear from Earth? Answer: (a) If the plants and animals disappear from the Earth’s surface, then the ecological balance will be disturbed. Without plants there will be no oxygen available for breathing after some time and everybody will die. These animal and plant species, including humans, are all interdependent. What […]
Is there any acceleration in uniform circular motion?
Is there any acceleration in uniform circular motion? In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant. Acceleration is in the direction of the change in velocity, which points directly toward the center of rotation—the center of the circular […]
