True lizards can stick to surfaces because their bulbous toes are covered in hundreds of tiny microscopic hairs called setae
Answer:
Explanation:
The rectangular components of a vector 
having a magnitude v and angle θ are:
The golf ball has an initial speed of 75 m/s at an angle of 60 degrees.
The variables of the equations have the values:
v = 75 m/s
θ = 60°
Substituting into the formula:
Without specifying units and with precision to the hundredths place:
Answer:
1. In a coal-fired power plant, chemical energy is first converted to thermal energy. TRUE.
The chemical energy in the coal is converted to thermal energy when the coal is burnt to produce steam.
2. In a coal-fired power plant, approximately 2/5 of original energy in the coal is lost to heat. FALSE.
Approximately 3/5 of the original energy is lost not 2/5 so this statement is false.
3. The molecules in cold air move faster than in hot air. FALSE.
Molecules with more heat move faster than molecules with less. Molecules in cold air therefore, will move slower than molecules in hot air.
Answer:
Explanation:
Given
Speed of ball 
Plane is inclined at an angle 
To win the Game we need to hit the target at 
away
Launch angle of ball 
Motion of ball can be considered in two planes i.e. Vertical to the plane and horizontal to the plane
So Net acceleration in vertical plane is 
Range of Projectile is given by
for 
so ball must be launched at an angle of 
C. Newton’s Third Law of Motion.
Because...
Newtons third law implies conversation of momentum it can also be seen as following from the second law: when one object pushes a second object at some point of contact using an applied force, there must be an equation of opposite force from the second object that cancels the applied force. Otherwise, there would be a nonzero net force on a massless point which, by the second law, would accelerate the point of contact by an infinite amount.
