A quadratic equation is a parabola and a linear equation is a straight line.
- Quadratic Equation is an equation in which the power of variable mostly x is two.
- Standard quadratic equation is
- Any linear equation have form like
- The moon has no atmosphere, no weather and no oceans of water. Its surface is in a perpetual vacuum.
- Because the moon's gravity is only one-sixth that of the Earth's gravity, Apollo astronauts had to risk of stumbling or falling.
- Astronauts on the moon were protected from the extreme temperatures by their spacesuits. The suits had several layers of insulating material covered by a highly reflective outer layer.

Answer:
Explanation:
magnetic field B = (3 i + 8 x 2 j )x 10⁻³ T
= (3 i + 16 j )x 10⁻³ T
L = - i ( unit length of conductor )
Force F = I ( L x B ) , I is current
= 5 [ - i x ( 3i + 16 j ) 10⁻³]
= 5 ( - 16 k ) x 10⁻³
F = - 80 x 10⁻³ k
1). trajectory
2). person sitting in a chair
3). 490 meters
4). 65 m/s
5). False. The projectile's displacement, velocity, and acceleration have vertical and horizontal components, but the projectile doesn't.
6). False
7). The vertical component of a projectile doesn't change due to gravity, but the vertical components of its displacement, velocity, and acceleration do.
The vertical components do NOT equal the horizontal components.
8). Decreasing if you include the effects of air resistance. Constant if you don't. Gravity has no effect on horizontal velocity.
9). We can't see the simulation. But if the projectile doesn't have jets on it, then as it travels upward, its vertical velocity must decrease, because gravity is trying to not let it get away.
10). We can't see the simulation. But if the projectile is traveling downward, we would call that "falling", and its vertical velocity must increase, because gravity is pulling it downward.
Answer:
Reaction is 20N.
Explanation:
In general, Newton's third law of motion explains that when a force is applied on an object, a reaction of equal magnitude applies in the reverse direction of the force.
i.e F = -R
This implies that, reaction is a force in the opposite direction to that of the force applied.
Force can also be related to the weight of an object as;
F = W = mg
Thus to prevent the 20N stone from falling, a force of 20N is applied in the opposite direction. So the reaction, R is 20N.
Answer:
Explanation:
From the question we are told that
Mass 
Velocity of mass 
Force of Tunnel 
Length of Tunnel 
Height of frictional incline 
Angle of inclination 
Acceleration due to gravity 
First Frictional surface has a coefficient 
Second Frictional surface has a coefficient 
Generally the initial Kinetic energy is mathematically given by
Generally the work done by the Tunnel is mathematically given as
Therefore
Generally the energy lost while climbing is mathematically given as
Generally the energy lost to friction is mathematically given as
Generally the energy left in the form of mass 
is mathematically given as
Since
Therefore
It slide along the second frictional region
