<h3><u>Answer;</u></h3>
B. 3.43 kPa
<h3><u>Explanation</u>;</h3>
Pressure is given by the formula;
Pressure = Force / Area
Force is the product of mass and acceleration due to gravity.
Thus; Force = mass x acceleration due to gravity
Substituting;
Force = (350 kg) x (9.8 m/s²)
Force = 3430 N
Then, using the first equation;
Pressure = 3430 N / 1m² or Pa
<h3> <u>= 3.43 kPa</u></h3>
Its VENUS because the planet is basicily a hot planet
Answer:
B
Explanation:
Solution:-
- Take a coordinate system as follows:
x: Directed along the ground
y: Directed vertical to ground
- We will assume that the initial vertical and horizontal non-zeroes velocities are given as follows:
- After a ball is thrown it continues a path of parabolic projectile. The motion of the ball can be analyzed in each coordinate system. We will assume that effects of air-resistance are negligible.
- Therefore, only gravity acts on the ball in the vertical direction. We can use kinematic equation of motions to determine the velocity of ball in either ( x-y ) direction at any instant of time ( t ).
- Use first kinematic equation of motion in both x and y directions.
- The accelerations ( ax and ay ) in the direction of each axis are to be determined. We know that the gravity acceleration ( g ) acts in vertical direction or along y-axis ( ay ) and always directed downwards while velocity is directed up. Since, we neglected the effects of air-resistance there is no acceleration in the x-direction ( ax = 0 ) .
- We see that the horizontal velocity of the ball ( vxf ) at any point in time remains equal to the initial horizontal velocity; hence, it is constant throughout the journey.
- However, the velocity of the ball in vertical direction( vyf ) is changing for every unit of time ( t ) under the influence of gravitational acceleration. Hence, it is not constant throughout the journey
