What else can I help you with?
Is it true or false that all muscles are made stronger by progressive resistance exercises?
It is false. NOT all muscles are made stronger by progressive resistance exercises.
True or false cells containing a plasmid with an antibiotic resistance gene will die in the presence of the antibiotic?
False. Cells containing a plasmid with an antibiotic resistance gene will survive in the presence of the antibiotic because they can produce the protein that confers resistance, allowing them to withstand the antibiotic's effects.
True of false The acceleration of an object is inversely proportional to the net force acting on it?
False. The acceleration of an object is directly proportional to the net force acting on it. Newton's 2nd Law: F = ma where F is the force, m is the mass, and a is the acceleration. __________________________________________________ The acceleration of a body is "inversely" proportional to its mass.
Is it true or false that Galileo believe that the natural state of an object was to be at rest?
False. Galileo believed that the natural state of an object was to be in motion. He famously challenged the Aristotelian idea that objects naturally came to rest.
Is Chilling a liquid will increase evaporation at the surface true or false?
It is not true.
Is it true or false that the greater the surface area of an object the greater the air resistance?
true
In free fall the object with less air resistance falls with a greater acceleration.?
False
True or false when an object rolls over a surface the kind of friction that occurs is called round friction?
False. The type of friction that occurs when an object rolls over a surface is called rolling friction, not round friction. Rolling friction is caused by the deformation of the object and surface at the point of contact, which generates resistance that opposes the motion of the object.
Air resistance is a type of friction True or False?
Air- resistance is basically a type of friction between an object and the air
What is an object with a greater density than water will float in water is it true or false?
False
Why big things have a bigger air resistance than small things?
You have a false premise. Not ALL big things have bigger air resistance than small things. Air resistance must also factor in the direction of movement and the surface area against which the air is impacting, i.e., the shape of the objects.
The inertia of an object is determined by its speed true or false?
False. The inertia of an object is determined by its mass, not its speed. Inertia is a property of matter that represents its resistance to changes in motion.
When the only force acting on falling object is air resistance the object is said to be in free fall True or false?
true
When the only force acting on a falling object is air resistance the object is said to be in free fall. true or false?
true
True or false the force needed to overcome kinetic friction is useally greater than that needed to overcome static friction?
False. The force needed to overcome static friction is typically greater than that needed to overcome kinetic friction. Static friction is the resistance to motion when an object is at rest, while kinetic friction is the resistance to motion when an object is already in motion. Static friction requires more force to overcome because it is necessary to break the initial "stickiness" between the surfaces.
Is itTrue or false is the greater the height of an object the greater its gravitational potential energy?
True. Gravitational potential energy is directly proportional to an object's height above a reference point. This means that the greater the height of an object, the greater its gravitational potential energy.
When the pressure at the bottom of a submerged object is greater than the pressure at the top of the submerged object a buoyant force is produced.?
FALSE
