A placekicker kicks a football upward at an angle of 30 and a speed of 5.0 m/s at what other angle will he have to kick a second
Flura [38]

Answer:60^{\circ}

Explanation:

Given

speed of ball u=5 m/s

launch angle \theta =30^{\circ}

Range of a Projectile R=\frac{u^2\sin 2\theta }{g}

Range will be common for two angles i.e. \theta [tex] and [tex]90-\theta

for \theta R=\frac{5^2\sin 2\cdot 30}{g}

R=2.209 m

For 90-\theta

90-30=60^{\circ}

R=\frac{5^2\sin 2\cdot 60}{g}

R=2.209 m

An electric field of 710,000 N/C points due west at a certain spot. What is the magnitude of the force that acts on a charge of
Anni [7]

Answer:

The magnitude of force is 4.26\times 10^{- 6} N

Solution:

As per the question:

The strength of Electric field due west at a certain point, \vec{E_{w}} = 710,000 N/C

Charge, Q = - 6 C

Now, the force acting on the charge Q in the electric field is given by:

\vec{F} = Q\vec{E_{w}}

\vec{F} = -6\times 710,000 = - 4.26\times 10^{- 6} N

Here, the negative sign indicates that the force acting is opposite in direction.

labwork [276]

Answer:

Accretion

Explanation:

Accretion is the process by which there is an accumulation of particles into a bigger object by attracting more mass by gravitational force into an accretion disk. This is one of the first steps in the formation of our solar system. There was a collapse of a gas cloud which resulted in most of the mass collecting in the center leading to the formation of the sun and the rest spread out forming the planets.
