Hi there,

Unlike velocity,speed is scalar,which means it is described by MAGNITUDE only.

Answer:

magnitude

Explanation:

There are two types of quantities.

Scalars: The quantities which are completely described by their magnitudes only are called scalars.

For example, mass, length, time, speed, temperature, etc.

Vectors: The quantities which are completely explained by their magnitude and direction both are called vectors. For example, velocity, weight, force, momentum, etc.

As speed is a scalar quantity so it can be completely described by their magnitude only.

Ball B is suspended from a cord of length l attached to cart A, which can roll freely on a frictionless, horizontal track. The b
Kazeer [188]

Answer:

a.Velocity of A and Velocity of B will be opposite in direction.

b.Both velocities have the same direction.

c. The two objects will move in a direction of some angle α.  

Explanation:

When the angle gets maximum the velocities of the two objects pull each other and move in opposite direction. But when the two objects make an angle zero degree with each other their motion is in the same direction.

an airplane releases a ball as it flies parallel to the ground at a height of 235m. if the ball lands on the ground exactly at 2
Oksanka [162]
<span>When the question says the ball lands a distance of 235 meters from the release point, we can assume this means the horizontal distance is 235 meters. Let's calculate the time for the ball to fall 235 meters to the ground. y = (1/2)gt^2 t^2 = 2y / g t = sqrt{ 2y / g } t = sqrt{ (2) (235 m) / (9.81 m/s^2) } t = 6.9217 s We can use the time t to find the horizontal speed. v = d / t v = 235 m / 6.9217 s v = 33.95 m/s Since the horizontal speed is the speed of the plane, the speed of the plane is 33.95 m/s</span>

What will be the pressure exerterd by the 0bject if 4000n is acting on an area of 50msqure
Ivahew [28]
<h3>Given, </h3>

Force,F = 4000 N

Area,a = 50 m²

<h3>We know that, </h3>

Pressure = Force/Area

★ Putting the values in the above formula,we get:

\sf \rightarrow \: pressure =  \dfrac{4000}{50}

\sf \rightarrow pressure = 80 \: N {m}^{ - 2}
