The initial speed doesn’t matter.  To reach the maximum height, you need to launch straight up ... 90 degrees above horizontal.

Answer:

90 degree

Explanation:

The height for the projectile motion is given by

H = u^2 Sin^2 theta/ 2g

Height is maximum when sin theta is maximum.

Sin theta is maximum when it's value is 1.

So the value of theta is 90 degree.

What is the scientific saying/principle that explains why a hammer and a screwdriver, both made of steel, are used for different
deff fn [24]

Hammer and screwdriver perform different tasks because they are both simple machines.

A machine is simply a device that can be used to perform a task. This  machine can be any physical system or device designed to perform a specific task.

The efficiency of the machine describes the easy with which each machine or tool is able to use input power to overcome a task.

Machines are designed to overcome a particular task with little effort in order to increase its efficiency.

Hammer and screwdriver, are both examples of simple machines.

Thus, Hammer and screwdriver perform different tasks because they are both simple machines.

I have four questions.
Inga [223]

Answer:

The potential energy of the ball is 784 joules. And the kinetic energy of it is 392 while falling halfway down.

Explanation:

PE = mass (2kg) * Gravitational acceleration (9.8 m/s^2)* height (40 meters)

KE = 1/2 mass (1 kg) * velocity^2 (19.8)

Two satellites A and B of the same mass are orbiting Earth in concentric orbits. The distance of satellite B from Earth’s center
riadik2000 [5.3K]

Answer:

ratio of tangential velocity of satellite b and a will be 0.707

Explanation:

We have given distance of satellite B from satellite A is twice

So r_b=2r_a

Tangential speed of the satellite is given by

v=\sqrt{\frac{GM}{r}}, G is gravitational constant. M is mass of satellite and r is distance from the earth

We have to find the ratio of tangential velocities of b and a

From the relation we can see that tangential velocity is inversely proportional to square root of distance from earth

So \frac{v_b}{v_a}=\sqrt{\frac{r_a}{r_b}}

\frac{v_b}{v_a}=\sqrt{\frac{r_a}{2r_a}}

\frac{v_b}{v_a}=\sqrt{\frac{1}{2}}

\frac{v_b}{v_a}=0.707

So ratio of tangential velocity of satellite b and a will be 0.707
