How do you find the horizontal speed? Divide Displacement by Time Divide the horizontal displacement by time to find the horizontal velocity. How do you find vertical and horizontal speed? Write down the equations of motion. Horizontal distance traveled can be expressed as x = Vx * t , where t is the time. Vertical […]

How do you ask a yes no question? It means when we are asking yes/no questions, we are expecting the answer, yes or no. To form Yes/No questions, we use one of these verbs: auxiliary verbs ( be, do and have ) or modal verbs ( can, may,etc.). We can not use questions words like […]

What part of your body is least sensitive? trunk Which part of skin is most sensitive? The face has demonstrated to be the most common site of skin sensitivity (Table 3), predictable physiologically due to the larger and multiple number of products used on the face (particularly in women), a thinner barrier in facial skin, […]

What is the example of vector quantity? For example, displacement, velocity, and acceleration are vector quantities, while speed (the magnitude of velocity), time, and mass are scalars. To qualify as a vector, a quantity having magnitude and direction must also obey certain rules of combination. Why is distance not a vector? Distance is a scalar […]

Are shoulders fast or slow twitch? For example, hamstrings should be trained with heavy weights and low reps because they’re 70% fast twitch, while the shoulders should be hit with low weights and high reps as they’re mostly slow twitch. Are abdominals slow or fast twitch? The abdomen (Abs) are muscles all the same to […]

Does momentum determine whether the egg breaks? B. Does the car’s momentum determine whether the egg breaks? Yes C. How does potential energy change when mass is increased? The amount of gravitational potential energy an object has depends on its height and mass. The heavier the object and the higher it is above the ground, […]

How many calories should I consume to lift 1 kg? It takes ~ 240 calories to raise or lift 100 kilograms 1 meter. Human energy calories are always kilocalories. If you wanted to burn 1000 (k)calories, you’d have to bench press 100kg about 830 reps. How many calories do you burn in 2 hours of […]

Does pure water have a pH of 7? Alkaline water has a pH of 8 or above. The most alkaline substances, such as lye, have a pH of 14. Pure water has a pH of 7 and is considered “neutral” because it has neither acidic nor basic qualities. Does boiling water reduce the pH? The […]

What cause the plates to move? The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift. How does temperature change as you go deeper into the earth? The Earth gets hotter as one travels […]

Will I get held back if I fail 2 classes? To fail a grade a student usually must fail two or more core classes or fail the standardized test in their state. Grade retention policies vary at both the state and district levels for students at-risk of being held back. To avoid this, they will […]
