Answer:
Acceleration is directly proportional to the net force
Explanation:
The net force acting on an object is given by :
F = ma
Where
m is mass
and
a is acceleration
It can be seen that the relation between the net force and the acceleration is direct i.e. as the acceleration increases, the net force will increase. Hence, the correct option is (d).
The angle between the incident ray and the reflected ray from a mirror is 720.
Find the angle of incidence.
Answer:
when a ray of light is incident normally on a plane mirror the angle between incident and reflected ray is 0 degree or 180 degree

There is a scale with a basket on it. A brick, brick #1 is placed on the scale. The brick has a mass of 10 kg. What are the two forces acting on the brick?
Answer:
Weight and reaction.
Explanation:
With respect to Newton's third law of motion, action and reaction have equal magnitude but acts in opposite direction.
Thus, the brick of mass 10 kg has its weight (due to gravitational pull of the earth), which acts downwards through its center of mass. This makes the scale to produce an opposing force of equal magnitude, which acts upwards. These two forces acting in opposite directions balancing each other.
The two forces acting on the brick are: its weight and the reaction from the scale.
Blake strikes a punching bag with 80N of force for 0.05 seconds. John strikes a
punching bag with 60N of force for 0.1 second. Who delivers a greater amount of
impulse?
Answer:
So impulse= force × timeP1= 80N× 0.05 = 4 P2= 60N × 0.1= 6 Hence John delivers a greater impulse I do exams and quizzes if your interestedName some minerals used as gems.

1. A stone is thrown upwards with an initial velocity of 25 m/s at angle of 30° to the ground a. Show that the vertical component if the velocity at the starting is 12.5 m/s upwards.
The vertical component of the velocity at the starting is 12.5 m/s upwards.
What is velocity?Velocity is the direction at which an object is moving and serves as a measure of the rate at which its position is changing as seen from a specific point of view and as measured by a specific unit of time.
In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a fundamental idea.
Given that stone is thrown upwards with an initial velocity of 25 m/s at angle of 30°.
Hence, the vertical component of the velocity in upward direction = 25 sin30° m/s
= 25 × 1/2 m/s
= 12.5 m/s.

Answer:
Bent knees
Explanation:
Depending the height your jumping from, if you were jumping from a high structure it's best if you jump and land on knees so you dont sprang your ankles from jumping and landing on your straight legs, you could even pull a muscle if you land on straight legs.

2, A rectangular Container of base 50 cm by 30cm is filled with water to be depth of 5cm. how much is the pressure exerted at the base? (take pw= 1000kg /m3 and g=10m/s)
Answer:
P = 500 N/m²
Explanation:
Pressure exerted at the base is the hydrostatic pressure and it is given by the formula;
P = ρgh
Where;
ρ is density = 1000 kg/m³
g = 10 m/s²
h is depth = 5 cm = 0.05 m
Thus;
P = 1000 × 10 × 0.05
P = 500 N/m²

how does a longshore current affect a beach?
Answer:
"Longshore currents are affected by the velocity and angle of a wave. When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. ... This process, known as “longshore drift,” can cause significant beach erosion."
