Which of the following is a declarative sentence
arsen [322]
Any multiple choice? I cant answer without possible answers.
But for insight a declarative sentence is a statement. For example: "I am going to the store." And Declarative sentences end with a period. (.)
Hope this helps. Just dont get confused with sentences that end in periods (.) but are really commands.

How high would a projectile go if it was launched from ground level with an initial speed of 26 m/s at an angle of 30 degrees ab
tigry1 [53]

Answer:

Vy = 26 m/s sin 30 = 13 m/s      vertical speed

t = Vy / a = 13 m/s / 9.80 m/s^2 = 1.33 sec     time to reach Vy = 0

H = Vy t + 1/2 g t^2

H = 13 m/s * 1.33 sec - 1.33^2 * 9.8 / 2 m = 8.62 m

How can one object affect the motion of another without touching it?​
stealth61 [152]

By non-contact forces (e.g. gravitational force and electric force)

Explanation:

In order for an object to exert a force on another object, the two object can also be not touching each other. In fact, there exist some non-contact forces in nature.

Concerning macroscopic objects, the two main non-contact forces acting between objects are:

- The gravitational force: this force is exerted between every object that has mass. It is always attractive, and its magnitude is given by

F=G\frac{m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

- The electric force: this force is exerted between objects that have electric charge. It can be either attractive or repulsive, and its magnitude is given by

F=k\frac{q_1 q_2}{r^2}

where:

k=8.99\cdot 10^9 Nm^{-2}C^{-2} is the Coulomb's constant

q_1, q_2 are the two charges

r is the separation between the two charges
