What is the relationship between angular velocity and linear velocity? The greater the rotation angle in a given amount of time, the greater the angular velocity. Angular velocity ω is analogous to linear velocity v. We can write the relationship between linear velocity and angular velocity in two different ways: v=rω or ω=v/r. What is […]

What type of image is formed by a convex mirror? Image formed by a convex mirror is always virtual and erect. When an object is placed at infinity, virtual image is formed at focus and the size of the image is smaller. Can we see real image? It can be seen that the image is […]

Are lumps of ice and rock that travel the expanse of our solar system? Asteroids are small lumps of rocks and ice which orbit the Sun like mini-planets. They are sometimes called planetoids because they were probably formed in the same way as the planets. It is believed that the Solar System formed from a […]

How does a thermostat work physics? When the room warms up, the gas in the bellows expands and forces the discs apart. The inner disc pushes against a microswitch in the middle of the thermostat turning the electric circuit (and the heating) off. As the room cools, the gas in the bellows contracts and the […]

Is DaVinci Resolve good for beginners? I love Resolve and it’s my main NLE but it’s definitely not great for beginners. As much as I hate premiere it’s the better NLE for beginners. It has the most basic layout and it can handle more codecs than any other NLE. How expensive is DaVinci Resolve? Blackmagic’s […]

Can you let a flat tire sit overnight? Yes it’s ok overnight.. dont drive on it..but depending on the weight of the car and the wheel rim design..it could cut into the tire… Just do not move the car. It will cause damage to the tire and could bend the rim. Can a car sit […]

What is the difference between a hypothesis and a law between a law and a theory? A hypothesis is a limited explanation of a phenomenon; a scientific theory is an in-depth explanation of the observed phenomenon. “Laws are descriptions — often mathematical descriptions — of natural phenomenon; for example, Newton’s Law of Gravity or Mendel’s […]

Is acetone acidic or basic? Acetone is slightly acidic because its conjugate base is stabilized by resonance and induction from the carbonyl. Acetone is very slightly acidic with a pka of 19. It’s alpha carbon can get deprotonated by a strong base such as NaOH to form an enolate. What is the PH of acetone? […]

How do you solve for Charles Law? Based on the definition of Charles’ law, we can write the Charles’ law equation in the following way: V₁ / T₁ = V₂ / T₂ , where V₁ and T₁ are initial volume and temperature, respectively. Similarly, V₂ and T₂ are the final values of these gas parameters. […]

Which of the following is not an end product of photosynthesis oxygen carbon dioxide water glucose? CO2​ is the raw material for photosynthesis and glucose and oxygen are the products. How many end products are in photosynthesis? three end products What three products go into photosynthesis? In photosynthesis, energy from light is used to convert […]
