Answer:

98 kg

Mass is given as 10 kg. Therefore, Weight = 10 kg * 9.8 m/s^2. Weight = 98 kg.m/s^2. = 98 Newtons.

The weight in newtons of a 10 kg mass on the earth's surface is 98 N.

<u>Explanation:</u>

Every object on the Earth experiences an acceleration of $9.8 m/s^2$ due to gravity. From the given,

Mass of the object = 10 kg

To calculate the weight of the object we have to multiply the given mass of the object by the acceleration due to gravity.

i.e. $Weight= Mass\times Acceleration \ due \ to \ gravity$

Acceleration due to gravity = $9.8 m/s^2$

On substituting the values,

Weight = $10 kg\times 9.8 m/s^2$

$(1 N = 1 kg. m/s^2)$

$\bold{\Rightarrow 98 \ kg.m/s^2\Rightarrow 98 N}$

Weight = 98 N

Describe a situation in which you can accelerate even though your speed doesn’t change.

KATRIN_1 [288]

Acceleration is not the same as speeding up. It refers to any modification of motion's direction or speed. Accelerated motion is any movement that is not constant speed in a straight line.

<h3>What is meant by acceleration?</h3>

The rate at which an object's velocity for time changes is referred to as acceleration in mechanics. They are vector quantities and accelerations. The direction of the net force acting on an object determines the direction of its acceleration.

An object's velocity can alter depending on whether it moves faster or slower or in a different direction. A falling apple, the moon orbiting the earth, and a car stopped at a stop sign are a few instances of acceleration.

The rate at which velocity changes is called acceleration. Acceleration typically indicates a change in speed, but not necessarily. An item that follows a circular course while maintaining a constant speed is still moving forward because the direction of its motion is shifting.

Let's examine over the next few questions an NFL kick as described in the 3rd Law video. The announcer claimed that the ball is

hichkok12 [17]

Answer:

8451.62109367671 Newtons

Explanation:

$1\ kg=1\times 9.8066500286389=9.8066500286389\ N$

$1 \lb=2.2046226218488\ kg$

It is known that

$1\ lbs=\dfrac{9.8066500286389}{2.2046226218488}=4.4482216282508\ N$

So,

$1900\ lbs=1900\times 4.4482216282508\\\Rightarrow 1900\ lbs=8451.6210936765\ N$

The force in Newtons is 8451.6210936765 Newtons

Beryllium has a charge of +2, and bromine has a charge of –1. Which is the best name for the ionic bond that forms between them?

postnew [5]

There are 2 elements:
Beryllium ( Be + 2 ), metal
Bromine ( Br - 1 ), non - metal
They form the ionic bond:
Be + Br2 → Be Br2
Naming the ionic compound:
on the 1st place is metal. On the 2nd place is non-metal. If compound is binary, use the element name and change ending to - ide .
Answer:
Beryllium Bromide.

A football player runs from his own goal line to the opposing team's goal line, returning to his forty-yard line, all in 22.4 s.

Bumek [7]

I assume L=120 yards as the length of the football field.

1) The average speed is given by the total distance covered by the player divided by the time taken.
The total distance covered to go from one goal line to the other and then back to the 40-yards line is
$S=120y+(120-40)y=120y+80y=200 y$
And the time taken is t=22.4 s, so the average speed of the player is
$v= \frac{S}{t}= \frac{200 y}{22.4 s}=8.93 y/s$

2) The find the average velocity, we should also consider the direction (and the sign) of the velocity.
In the the first part of the motion, the player goes from one goal line to the other one, so he covers 120 y. However, in the second part of the motion he goes back by 80 y. Therefore, the net displacement of the player is
$S=120 y-80 y=40 y$
and so, the average velocity is
$v= \frac{S}{t}= \frac{40 y}{22.4 s}= 1.79 y/s$
