Does changing the mass affect acceleration? Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass. How does changing force […]
What happens in the body negative feedback temperature control system?
What happens in the body negative feedback temperature control system? Negative feedback is a vital control mechanism for the body’s homeostasis. When body temperature drops, the hypothalamus initiates several physiological responses to increase heat production and conserve heat: Narrowing of surface blood vessels (vasoconstriction) decreases the flow of heat to the skin. How do you […]
Is green light healthy?
Is green light healthy? Green light therapy, fibromyalgia, and other pain-related conditions. It’s not just migraine, but chronic pain conditions that may be helped by green light therapy. For example, green light was shown to have a positive effect on pain from fibromyalgia—a condition marked by widespread pain, sleep problems, and fatigue. Does green light […]
Why is it a good idea to start with room temperature water in the calorimeter?
Why is it a good idea to start with room temperature water in the calorimeter? It is a good idea to start with room temperature water in the calorimeter because the room temperature water helps to determine the heating up/cooling down because of the environment as the experiment takes place. Because the calorimeter heat is […]
What is the example of vector quantity?
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 […]
Can we measure distances in micrometers?
Can we measure distances in micrometers? Depending on the type of micrometer available, a variety of distances can be measured. It could measure the diameter of a hole, the length of the surface of a nail or the depth of a slot. Standard micrometers will measure objects less than one inch in length/depth/thickness. Which is […]
Which is faster rolling or sliding?
Which is faster rolling or sliding? Since the sliding object has no angular velocity, its linear velocity is greater than that of the rolling object, and it reaches the bottom of the track faster. And if C < μk, the rolling object has a greater linear acceleration and wins the race to the bottom. What […]
What are two differences between heat and temperature?
What are two differences between heat and temperature? Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Heat measures how energy moves or flows. Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or […]

Can the president do anything without Congress approval? Executive powers The president can issue rules, regulations, and instructions called executive orders, which have the binding force of […]
What happens if you dont shear a sheep?
What happens if you dont shear a sheep? Unlike other animals, most sheep are unable to shed. If a sheep goes too long without being shorn, a number of problems occur. This can cause sheep to become overheated and die. Urine, feces and other materials become trapped in the wool, attracting flies, maggots and other […]
